Overview
Moving from SupportSystem to Zendesk is a CSV-first migration with API-driven destination loading. SupportSystem exposes no REST API, so all source data extraction relies on CSV exports from the Agent Panel filtered by date range, queue, or Advanced Search. We batch those exports, verify custom field presence in the Export Picker before processing, and load the resulting records into Zendesk via the Zendesk REST API with rate-limit handling and parent-record lookup resolution. We preserve Help Topic routing as Zendesk Views, map custom form fields to Zendesk custom fields, and flag that binary attachment files are excluded from SupportSystem CSV exports and require separate manual handling. Workflows, macros, and automations do not migrate as code; we deliver a written inventory for the customer admin to rebuild in Zendesk.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a SupportSystem object lands in Zendesk, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
SupportSystem
Ticket
Zendesk
Ticket
1:1SupportSystem Tickets map directly to Zendesk Tickets. We extract ticket metadata via CSV from the Agent Panel (Ticket ID, status, subject, description, creation date, update date, assignee, priority, Help Topic, custom field values) and load into Zendesk via the Tickets API endpoint POST /api/v2/tickets. The SupportSystem ticket ID is preserved in a Zendesk custom field for cross-reference. Ticket status mapping: Open/Overdue to Open, Resolved to Solved, Closed to Closed.
SupportSystem
Agent
Zendesk
User (Agent)
1:1SupportSystem Agents export as part of ticket header CSV or via Advanced Search filtered by Agent. We extract name, email, and Department assignment per agent and create Zendesk User records with role=agent. The SupportSystem Department becomes a Zendesk custom field or group membership depending on whether the customer uses Zendesk Groups for routing. Agents without email in SupportSystem require manual email address entry before migration.
SupportSystem
User (End User)
Zendesk
User (End User)
1:1SupportSystem End Users (requesters who create tickets via the Client Portal) export via Advanced Search filtering by User Information. We map to Zendesk End Users with name, email, and any user-level custom fields. Zendesk End Users do not require a paid seat and can be bulk-imported via CSV to the Users API. We preserve any Organization assignment from SupportSystem as a Zendesk Organization lookup.
SupportSystem
Organization
Zendesk
Organization
1:1SupportSystem Organizations are a distinct object referenced on tickets. Organization records export via Advanced Search under Organization Information or as part of ticket header CSV. We map Organization name, domain, and any organization-level custom fields to Zendesk Organizations via the Organizations API. Zendesk requires Organizations to exist before Users can be linked to them, so we load Organizations before User records.
SupportSystem
Custom Field
Zendesk
Custom Field
lossySupportSystem Custom Fields per ticket, user, or organization require Export Picker configuration before each CSV export run. We verify which custom fields are present in the sample CSV before processing the full dataset. Missing fields require a re-export with updated picker settings. Zendesk custom fields are created in Admin Center under Objects and Rules before import; drop-down and multi-select values can be bulk-imported via CSV with a 3,500 row limit per import file. We handle text, numeric, date, and checkbox field types with direct value mapping.
SupportSystem
Custom Form
Zendesk
Custom Field (ticket field)
lossySupportSystem Custom Forms collect structured data at ticket creation. Form field responses export as part of ticket CSV when the Export Picker includes form fields. We map form field names and response values to Zendesk ticket custom fields, creating new custom field definitions in Zendesk Admin Center if the destination fields do not already exist. Form logic and conditional field display do not migrate; we document the form structure for the admin to rebuild as Zendesk ticket fields.
SupportSystem
Help Topic
Zendesk
View (or Custom Field)
lossySupportSystem Help Topics drive ticket routing and can trigger specific Custom Forms. Help Topic assignment appears in ticket metadata. We preserve Help Topic routing by creating Zendesk Views that filter tickets by the Help Topic custom field value, replicating the queue visibility logic. For organizations that rely on Help Topic as a reporting dimension, we map Help Topic names to a Zendesk multi-select custom field or tag set. We do not migrate Help Topic form-trigger associations as automation; we deliver a written map of these for the admin to rebuild in Zendesk Triggers.
SupportSystem
Department
Zendesk
Group
1:1SupportSystem Departments assign agents and route tickets. Department data appears in ticket header exports. We map SupportSystem Department names to Zendesk Groups, creating Group records in Zendesk Admin Center and associating agents with the corresponding Group. Ticket routing by Department maps to Zendesk Views filtered by assignee Group membership.
SupportSystem
Custom List
Zendesk
Drop-down or Multi-select Custom Field
lossySupportSystem Custom Lists are reusable data sets added to tickets or Help Topics. List values export as part of custom field data when form fields are included in the CSV. We handle list-to-dropdown mapping by creating Zendesk drop-down or multi-select custom fields and populating the allowed values from the SupportSystem list data. If a list has more than 3,500 distinct values, we split across multiple imports or recommend a tag-based approach in Zendesk.
SupportSystem
Tag
Zendesk
Tag
1:1SupportSystem Tags applied to tickets appear in ticket metadata exports. We preserve tag strings and create matching Tags in Zendesk. Tag-based reporting in SupportSystem maps to Zendesk tag-based Views or the Explore reporting tool. Tags with no corresponding value in Zendesk are created at import time.
SupportSystem
KB Article
Zendesk
Article (Zendesk Guide)
1:1SupportSystem Knowledge Base articles export as structured text with category and internal link metadata. We extract article content, title, author, and category assignment and map them to Zendesk Guide Articles under the corresponding Section and Category. Internal links require review and update post-migration because article IDs change in Zendesk. We do not migrate article permission settings or translation data as structured records; we document the locale configuration for the admin to set in Zendesk Guide.
SupportSystem
Email Template
Zendesk
Macro (Macro Body)
1:1SupportSystem stock and custom email templates exist per department. Template content exports as structured text from the platform. We extract template body, subject, and department association and map them to Zendesk Macros under the corresponding Group. Zendesk Macros are configuration objects, not records; we deliver a written inventory of the template content and recommended Macro placement for the admin to create and assign in Zendesk Admin.

Migration approach
Scoping and CSV extraction planning
We audit the SupportSystem environment: ticket volume, active date ranges, custom fields in use, Export Picker configuration, and whether Organizations, Help Topics, and Knowledge Base articles require migration. We coordinate with the customer to scope CSV export runs filtered by date range or queue to stay within the Export Picker's field limits. We verify custom field presence in sample exports before committing to the full extraction schedule.
Zendesk environment preparation
We prepare the Zendesk destination environment: creating Groups (mapped from SupportSystem Departments), custom fields (mapped from SupportSystem custom fields and form fields with type-matched Zendesk field definitions), and any drop-down or multi-select field value lists. If the customer requires Help Topic routing replication, we design Zendesk Views filtered by Help Topic custom field values. We also configure the Help Center (Guide) if Knowledge Base articles migrate.
CSV extraction and data validation
The customer runs CSV exports from the SupportSystem Agent Panel per our extraction schedule. We review each exported CSV for completeness: ticket header fields, custom field values, user and organization records, and any Help Topic or Department metadata. We flag missing custom fields, incomplete user records (missing email), or orphaned organization references before processing. Validation reports are shared with the customer for sign-off before batch processing begins.
Record dependency ordering and batch processing
We load records into Zendesk in dependency order: Organizations first (no dependencies), then Users (Agents and End Users with Organization lookup resolved), then Tickets (with User, Organization, Group, and custom field references resolved). CSV batches are processed via the Zendesk REST API with rate-limit handling and exponential backoff. Each batch emits a row-count reconciliation report. Parent-record lookups (AccountId on Contact, OrganizationId on User) are resolved at load time using pre-mapped reference tables.
Custom field and value migration
We load SupportSystem custom field values into Zendesk custom fields. Drop-down and multi-select field values are imported via CSV to Zendesk Admin Center with batches split at the 3,500-row limit. Ticket-level custom field values migrate as part of the ticket load. We validate that all mapped field values appear in the Zendesk field's allowed-values list and flag any unmapped values for the customer's admin to add or map before final import.
Knowledge Base article migration
SupportSystem Knowledge Base articles export as structured text. We extract article title, body, author, and category metadata and map them to Zendesk Guide Articles under the corresponding Section and Category. Internal links in article bodies are flagged for manual update post-migration because Zendesk assigns new article IDs. Article permission settings and translation data are documented separately for the admin to configure in Zendesk Guide settings.
Cutover, validation, and handoff
We freeze SupportSystem writes during cutover, run a final delta export of any tickets modified during the migration window, and load remaining records into Zendesk. We deliver a row-count reconciliation report covering all migrated objects against source CSV totals. We deliver the automation inventory (Help Topic-to-View mapping, Email Template-to-Macro document) for the customer's admin to rebuild Triggers, Macros, and routing automations in Zendesk. We do not rebuild workflows, macros, or automations as part of the migration scope.
