Moving to Freshdesk or Freshservice? Preserve ticket structure, workflows, and automation with accurate data mapping. Your new system runs like your old one—no downtime, no broken processes.

Why data mapping matters

Proper mapping is crucial for a smooth help desk migration. It ensures data lands correctly, preserving ticket structure and workflows. Key benefits:

  1. Protects ticket context, history, and attachments
  2. Maintains workflows and automation
  3. Keeps required fields accurate
  4. Reduces errors in ticket handling
  5. Preserves reporting and SLA tracking

What can be mapped?

Field mapping is available for:

  • Freshdesk: tickets, customers (contacts), organizations
  • Freshservice: incidents, problems, changes, customers, organizations

You can map both default fields and custom fields.

Understanding default, system, and custom fields

Fields in Freshdesk and Freshservice fall into three categories:

System Fields

  • Examples: Subject, Tags, Organization, Group, CC, Assignee, Contact, Comments, Created date, Updated date, Closed date
  • Their mapping cannot be modified

Default Fields

  • Examples: Type, Source, Priority, Status
  • Can be adjusted if needed
  • Automatically mapped when the Source and Target share the same structure

Custom fields

Custom fields help align your migration with existing workflows. Mapping behavior by type:

  • Drop-down: Predefined options; mapped as drop-downs
  • Checkbox: Shown as drop-downs; migrate as checkboxes if compatible
  • Multi-level: Displayed as drop-downs; restored as multi-level when mapped correctly
  • Multi-select: Shown as drop-downs; becomes a multi-select if types match
  • Text/String: Single or multiline; mapped without length checks
  • Numeric: Map to numeric or text (with caution)
  • Date: Requires proper format (date-only or date-time)

Best Practices for Accurate Mapping

  • Create all required fields in the target system before migration.
  • Ensure field types match (text → text, numeric → numeric, etc.).
  • Review structured fields like drop-downs, multi-level, or multi-select to align options.
  • Map all required fields; missing mappings can block ticket migration.

Data mapping with Help Desk Migration apps

The Help Desk Migration app simplifies the process with automation and flexibility.

Automatic Mapping

  • Identical field names map automatically
  • Supports default and custom fields
  • Preserves options for drop-downs, multi-level, multi-select, and checkboxes

Flexible Mapping Controls

  • Skip field: Leaves non-required fields empty
  • Default value: Fills in when the source is empty, or the fields don’t align

Create Fields in the Migration Wizard

For Freshdesk and Freshservice:

  • Custom fields can be created directly during setup
  • Drop-down fields retain the same predefined options
  • Checkbox, multi-level, and multi-select fields are created as drop-downs on the target

Final Takeaway

Data mapping is the foundation of a successful help desk migration. Set up fields in advance, align types, and validate mappings to preserve ticket structure, maintain workflows, and avoid data loss.
