Why merge or split Zendesk® instances

Organizations merge Zendesk® accounts after mergers and acquisitions, internal consolidation, or when reducing the overhead of maintaining multiple systems.

Teams choose to merge Zendesk® instances when:

You acquired another company and need to merge Zendesk® accounts so agents can see and reply with full historical context intact.

Teams need shared visibility and unified reporting dashboards across all support functions after Zendesk® instance consolidation.

Multiple Zendesk® instances lead to duplicated workflows, redundant automations, and gaps in reporting accuracy.

By choosing to merge Zendesk® instances, teams eliminate duplicate workflows, reduce automation sprawl, and centralize SLA management while preserving historical data and minimizing disruption.

Splitting Zendesk® instances becomes essential when brands, regions, or compliance obligations require independence.

Teams separate Zendesk® instances when:

Workflows or SLAs conflict between departments or geographic regions.

Teams need operational autonomy to meet local regulatory or compliance requirements.

Separate reporting or branding is required for customer-facing support experiences.

This controlled Zendesk® migration approach reduces workflow conflicts, misrouted tickets, and reporting errors, while giving departments or brands the freedom they need.

Why Zendesk® to Zendesk® Migration Feels Risky (and How We Remove the Risk)

A Zendesk® to Zendesk® migration feels risky when done without visibility or validation.

Risk: Losing critical data

The thought of tickets, attachments, private notes, call recordings, or historical context being lost is enough to make teams hesitate. One wrong click could feel irreversible.

How Help Desk Migration handles it:

Our data migration service ensures every ticket, attachment, and conversation is migrated accurately. Demo migrations let you see your real data move safely before committing. Nothing is left behind, nothing breaks.


Risk: Downtime and disrupted support

Your agents continue to work, and your customers continue to reply. Support interruptions are unacceptable during Zendesk® instance consolidation.

How Help Desk Migration handles it:

All Zendesk® data migrations run in the background while Zendesk® stays live. During the Delta migration, you can migrate the new activity, so support never stops, and SLAs remain intact.


Risk: Broken workflows, misrouted tickets, and incorrect mapping

Incorrect brands, forms, assignees, or statuses can stall teams and introduce confusion, miscommunication, and reporting errors during Zendesk® instance consolidation.

How Help Desk Migration handles it:

Migration Wizard helps you map tickets, users, custom fields, macros, and triggers precisely. Edge cases such as merged tickets, follow-ups, or suspended users are handled automatically. You validate every mapping step, reducing risk to zero.


Risk: Cost, reporting continuity, and historical context

Migrating too much data can increase cost. Explore reports are not migrated by default. Attachments, screenshots, or notes could be missed.

How Help Desk Migration handles it:

Our data migration service lets you filter tickets and data, preserve reporting integrity, and capture every relevant historical detail. You stay in control of scope and cost.

What once felt risky becomes predictable, safe, and reversible. Agents keep working, customers keep getting replies, and leadership gets the confidence that the Zendesk® to Zendesk® switch will succeed.

With a Help Desk Migration Demo, you don’t guess but see it working before it matters.

How Zendesk® to Zendesk® Migration Works

Prepare · Map · Test · Go-live · Validate

Prepare

A successful Zendesk® to Zendesk® transfer begins with detailed preparation:

  • Select the target Zendesk® instance (merge or split) based on business requirements.
  • Align brands, forms, groups, and SLAs to match your intended architecture.
  • Confirm admin-level access to both source and target Zendesk® instances.
  • Define the migration scope: full history or only recent and open tickets.
  • Inventory all custom fields, macros, triggers, and automations, including dependencies.
  • Identify archived tickets, merged tickets, suspended users, and edge cases that may require custom handling.

Map

Mapping defines exactly how data behaves after the migration:

  • Tickets: statuses, brands, forms, assignees.
  • Users and organizations: deduplication, multiple-company associations, suspended user handling.
  • Custom fields: dropdown normalization, tag behavior, and multi-form field handling.
  • Rules: macros are fully migrated; automations are disabled during migration and re-enabled manually.

Test

Testing confirms accuracy and builds trust:

  • Migrate 20 real tickets including edge cases like multi-brand tickets, merged users, and follow-ups.
  • Review conversations, attachments, custom fields, and statuses for consistency.
  • Refine mapping based on results and rerun Demo migrations if needed.

Go-live

Full Migration runs while your source Zendesk® stays live:

  • Delta migration helps to move the new replies and agent updates during the cutover.
  • Agents continue their workflows, and customers continue receiving support.
  • Migration operates in the background to maintain full operational continuity.

Validate

This is a controlled customer service data migration process, not a self-serve gamble:

  • Reconcile ticket and user counts to confirm all data migrated correctly.
  • Rebuild Explore reports, as reporting data is not migrated by default.
  • Re-enable automations intentionally to prevent unexpected triggers.
  • Archive the source instance for compliance or record-keeping needs.
  • This is a controlled customer service data migration process, not a self-serve gamble.

Common Zendesk® to Zendesk® Migration Issues We Handle

Issue 1: Inactive or default brands causing misrouting

Problem:

Inactive brands on the source instance may default to a selected brand on the target, potentially mixing tickets across brands.

Solution:

Help Desk Migration service filters and maps inactive brands according to your requirements, ensuring tickets land in the correct brand without confusion.


Issue 2: Dropdown fields generating unnecessary tags

Problem:

Dropdown fields across multiple ticket forms can create unwanted tags after migration.

Solution:

Tailor mapping to remove irrelevant fields and optionally disable content auto-tagging, reducing tag noise while preserving critical data.


Issue 3: Archived tickets not appearing in views

Problem:

Archived tickets exist in the system but do not appear in default views, leading to concerns that “tickets were lost.”

Solution:

All archived tickets are included in the data migration, and we guide you on confirming them via ID search or wildcards.


Issue 4: Solved vs Closed ticket discrepancies

Problem:

Solved tickets may auto-close after 28 days, impacting status tracking.

Solution:

We account for Zendesk® automation behavior and you can map ticket statuses so historical records remain accurate, while you control future automations.


Issue 5: Timezone differences / UTC conversion

Problem:

API uses UTC; ticket timestamps can appear shifted by an hour after migration.

Solution:

Our service handles timezone normalization and provides post-migration verification to ensure timestamps align with your team’s local settings.


Issue 6: Light agent limitations

Problem:

Light agents cannot own closed tickets or post public comments, limiting how tickets appear in assignments.

Solution:

We pre-map light agent tickets and comments to appropriate agents, avoiding gaps in accountability.


Issue 7: IP restrictions or connection errors

Problem:

Migration tools can fail if source or target Zendesk® instances restrict certain IPs.

Solution:

We guide IP whitelisting and secure configuration to prevent failures.


Issue 8: Zendesk® search index mismatches

Problem:

Search-based ticket counts may not match actual ticket counts.

Solution:

Help Desk Migration Wizard validates counts via API data, and we can assist with reindexing if required.


Issue 9: Custom ticket statuses

Problem:

Only custom or default statuses can be mapped at once.

Solution:

We guide the client on disabling custom statuses and reconnecting the account, ensuring correct ticket status mapping.

Help Center (Knowledge Base) Migration

Help Desk Migration transfers articles, translations, hierarchy, attachments, and metadata between Zendesk® Help Centers while respecting platform limitations. Follow the guidelines below to ensure a complete and error-free migration.

Migration will fail if the API user lacks the necessary permissions:
  • Guide Admin role required for all Help Center content.
  • Access to all brands being migrated.
  • Permission to manage languages and locales.
  • Access to view archived or draft articles if they need migration.

  • Each brand must be migrated separately using its brand URL.
  • Multi-brand migrations are supported but tracked individually.
  • If articles in different brands share slugs or IDs, they are renamed during migration to prevent conflicts.

Rules to prevent migration errors:
  • Default language must match between source and target.
  • One-to-one locale mapping only. Multiple source locales cannot map to a single target locale.
  • Deleted locales in the source may still exist in the API; migrating these will fail.
  • Zendesk® UI locale names may differ from API codes (e.g., fr-fr → French, fr → French (France)). Verify in Knowledge Admin → Settings → Language Settings.
  • Articles without a default language are skipped unless assigned manually or via migration settings.
  • Specific locales can be skipped if not needed.

  • Draft and published articles: Migration preserves state. Drafts remain drafts; published articles remain published.
  • Archived articles: Cannot be migrated. Restore as draft or published first.
  • Folders & sections: Articles without folders are moved to a default folder. Section/category limits and maximum nesting depths are preserved but must be checked to avoid silent failures.
  • Sorting and pinned articles: Order is preserved where possible; custom positions may require post-migration adjustment.

  • Images, files, tags, and formatting are migrated as-is.
  • Embedded videos require unsafe content to be enabled in Zendesk®.
  • Links inside articles are updated if Update Crosslinks is enabled; otherwise, redirects must be manually configured.

  • Labels and tags are preserved.
  • Custom article fields may need mapping; unsupported fields are skipped.
  • Author attribution: Original authors are preserved if users exist in the target; otherwise, migration assigns the API user.
  • Article creation and update dates are maintained where possible.

  • Update Crosslinks preserves internal links.
  • Redirects are required if crosslinks are disabled.
  • Slugs are renamed automatically if duplicates exist in the target Help Center.

  • Migration is idempotent if the same articles are migrated again: updated articles overwrite previous versions.
  • Deleted articles or removed translations in the source are not automatically removed from the target.
  • Provide a list of articles for selective migration. If fewer than 20, this can be done in a demo using Demo with Custom Data.

  • Archived articles (restore first to draft or published).
  • Channel field data.
  • Spam tickets (Suspended tab).
  • Certain unsupported custom fields.

  • Newly migrated content may take time to appear in search results.
  • Indexing delays are normal and should be expected after migration.
What cannot be migrated?
  • Archived articles: Even custom ones cannot be migrated. To include them, you must first restore them as draft or published articles.
  • Channel field data: Zendesk® does not allow migration into the channel field, so this information cannot be moved to the default field.
  • Spam tickets: Tickets in the Suspended tab are not migrated.
Your knowledge base is fully structured, searchable, and retains historical integrity without your team manually handling thousands of articles.

Zendesk® to Zendesk® Migration FAQs:
Technical Details That Matter

Yes. All tickets migrate, including those from inactive brands. You control which brands and ticket forms are included, so tickets arrive in the correct brand or department.

Merged tickets are migrated as individual records, retaining complete historical context. Follow-ups can either be consolidated into the main ticket or captured in custom fields, based on your workflow requirements.

Unassigned tickets are automatically assigned to a default agent. This ensures no tickets are left orphaned and workflows continue without interruption.

Dropdown fields from multiple ticket forms are converted into tags. We minimize unnecessary tag creation while preserving all critical data. Auto-tagging can be disabled if preferred.

Yes. Call recordings are preserved as MP3 attachments, while all inline images, videos, and files migrate intact and usable in the destination instance.

All macros, triggers, and their conditions are migrated. Because skipping actions can cause triggers to fail, we verify everything before cutover. You can filter by active or inactive status, category, or group as needed.

Private notes created by non-agents, requesters, or CCs are reassigned to a default agent. The original context is preserved, so nothing is lost.

Avoid surprises, lost data, and downtime. Every ticket, user, macro, and knowledge base article migrates reliably. Demo migrations let you preview results, edge cases are handled automatically, and workflows stay uninterrupted.

Yes. Any tag applied to a user or organization is automatically added to new tickets created for them.

Default roles include End-User, Agent, and Administrator. With the Enterprise plan, you can create custom roles to fit your team’s needs.

This usually means the user running the migration doesn’t have permission to access help_center/user_segments. To fix this, assign the user the Help Center Manager role.

Knowledge Base articles can only be stored in folders, not categories. If an article doesn’t belong to a folder on the source system, it will be migrated into a default folder created by the migration tool.

Automations run based on time-based events, while triggers run in response to ticket creation or updates.

Yes. Tickets migrate from all brands, including deactivated ones. The Brand field appears on the mapping. If a brand is inactive, it does not appear on the mapping. Tickets from that brand will migrate to the default brand selected by the client. If a client wants to migrate only specific brands rather than all, filtering is required. On the target Zendesk®, tickets can be migrated to a specific brand by selecting it in the ticket mapping (the Brand field is displayed on mapping).

A ticket form is a template that defines which fields appear on a ticket, differentiating tickets by department or request type.
  • Form mapping: Ticket forms can be mapped between source and target.
  • Dropdown fields: Values from dropdowns on other forms are automatically added as tags by Zendesk®. This behavior cannot be prevented.
  • Custom mapping: Unneeded fields can be excluded to reduce tags.
  • Disabling tags: Zendesk® can disable automatic tagging; content-based auto-tags (Guide) can also be disabled, but dropdown field tags remain unless removed from mapping.

Merged tickets: Migrate as separate tickets. Private messages indicating the merge migrate as private messages. Follow-ups: Migrate as a single ticket. Follow-ups with IDs can optionally be migrated to a private note or a custom field.

Yes, archived tickets migrate by default. In Zendesk®, archived tickets are those in Closed status for 90 days.

Unassigned tickets on the target Zendesk® are assigned to a default agent.
  • Tickets can only remain in New status if unassigned.
  • When a New ticket is assigned to the default agent, Zendesk® automatically changes its status to Open.
  • Therefore, New status is excluded from migration mapping to Zendesk®.

Zendesk® lets you create custom ticket statuses beyond the defaults (New, Open, Pending, On-Hold, Solved, Closed).
  • Mapping: Either default or custom statuses are shown for mapping, never both at the same time.
  • Switching to default statuses: To map default statuses, deactivate custom statuses in your account and reconnect.
  • Ticket behavior: Tickets in custom statuses are treated as closed—they retain all closed-ticket characteristics (cannot be edited, remain in the Closed category) even if automations exist, but their status name does not change.

Yes. Organizations can be excluded if desired, preferably without informing users beforehand.

Yes. Contact (user and organization) tags are migrated by default. All tags associated with users or organizations in the source Zendesk® are transferred to the target instance and remain available for workflows, triggers, and reporting.

On Zendesk®, a ticket cannot belong to a company different from the requester's company. If a source ticket has a company different from the contact (or no contact company), it is possible to custom migrate multiple companies from tickets to the contact and reflect the correct company in the ticket.

Suspended users are extracted and migrated as unsuspended, because tickets cannot be created by suspended users. If a user exists on the target as suspended, we unsuspend and map them.

Zendesk® user segments can only be migrated via custom tag mapping for users and organizations. Clients must create user segments on the target for migrated contacts before or after migration. When migrating articles, source and target user segments are displayed for mapping, but they only work if configured correctly on the target.

If an agent belongs to Group A on the source and Group B on Zendesk®, the agent is assigned to the group linked to the ticket, according to the mapping.

Yes, tickets can be filtered by recipients (support emails) only if the domain is Zendesk®.

Triggers run automatically when their conditions are met. During migration:
  • Automated mapping: All triggers are migrated.
  • Reviewable details: Every condition and action is displayed for verification.
  • Critical: If any action is skipped, the trigger will fail after migration.

During migration, macros are transferred with all their core components and must be fully mapped to function correctly on the target Zendesk®:
  • Available for — defines which roles can use the macro.
  • Title — the macro’s name.
  • Body — the content or instructions applied by the macro.
  • Actions — all macro actions are mapped explicitly. If any action is skipped or left unmapped, the macro will fail after migration.
All macro actions, conditions, and dependencies are fully visible during the mapping stage, allowing you to validate and adjust them before go-live.

Yes. You can filter by:
  • Macros: active/inactive status, category, or group. By default, all macros migrate.
  • Triggers: active/inactive status or category. By default, all triggers migrate.
