Overview
Moving from Zendesk Sell to Zoho CRM is time-constrained by Zendesk's sunset deadline of August 31, 2027, making early-start migration windows (12-18 months out) the safest path to avoid data deletion. Zendesk Sell stores Companies as a distinct object; Zoho CRM uses Accounts for the same concept, so we map Company records directly to Accounts during import. Deals carry pipeline and stage assignment as separate properties that require explicit mapping to Zoho's pipeline and stage schema before migration. We handle Sell's parent-to-child dependency chain (Leads, Contacts, Accounts, Deals, Activities) in strict order, resolving custom field IDs to field keys during scoping, and we flag Sequences, Line Items, and custom objects that require rebuild in Zoho Blueprint and Deluge rather than direct migration. Activity history (calls, emails, meetings, tasks) migrates as Zoho Events and Tasks with timestamps and owner assignment preserved.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Zendesk Sell object lands in Zoho CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Zendesk Sell
Leads
Zoho CRM
Leads
1:1Zendesk Sell Leads map directly to Zoho CRM Leads, including all standard fields (name, email, phone, lead source, unqualified reason) and custom Lead fields. We resolve custom field IDs to field keys during scoping and create matching custom fields in Zoho before import. The lead_source property maps to the Zoho Lead Source picklist; any values not in Zoho's default list are added as custom picklist entries during configuration.
Zendesk Sell
Contacts
Zoho CRM
Contacts
1:1Contacts migrate 1:1 to Zoho Contacts with standard fields (name, email, phone, address) and all custom Contact fields preserved. Zoho Contacts must attach to an Account (Company) record; we resolve the parent Account reference by matching the associated Zendesk Sell Company name to the Account we create during the Account phase. Duplicate detection rules are applied during import to prevent duplicate Contacts.
Zendesk Sell
Companies
Zoho CRM
Accounts
1:1Zendesk Sell Companies map to Zoho CRM Accounts. The Company name becomes Account Name, domain becomes Website, and industry classification maps to the Industry picklist. Account is created before Contact import so the Account-Contact lookup relationship is satisfied at the moment of Contact insert. We use Company name as the dedupe key during import.
Zendesk Sell
Deals
Zoho CRM
Deals
1:1Deals migrate to Zoho CRM Deals with stage, amount, closing date, loss reason, and deal source preserved. The Zendesk Sell pipeline and stage assignment map to Zoho CRM's Pipeline and Stage fields. We pre-create Zoho pipeline stages matching the names and ordinal positions from Zendesk Sell during configuration. Closed-Lost reason from Zendesk custom fields becomes a Zoho Loss Reason text field.
Zendesk Sell
Pipeline
Zoho CRM
Pipeline
lossyZendesk Sell Pipelines map to Zoho CRM Pipelines. We pre-create pipelines in Zoho during the configuration phase, matching the pipeline name and assigning a Display Order that corresponds to the Zendesk Sell pipeline ordinal. Each Zoho pipeline gets its own Stages matching the source. If Zendesk Sell has multiple pipelines, we create corresponding Zoho pipelines and map deal-stage assignments accordingly.
Zendesk Sell
Stage
Zoho CRM
Stage
lossyStages are children of Pipelines in Zendesk Sell. Their ordinal position, loss flag, and win flag map to Zoho CRM Stage name, stage order, and stage type (open, won, lost). Probability percentages from Zendesk Sell migrate to Zoho Stage Probability fields. Stage mapping is validated during sandbox migration before production import begins.
Zendesk Sell
Tasks
Zoho CRM
Tasks
1:1Tasks with due dates, assignees, status, and priority migrate directly to Zoho CRM Tasks. We resolve task owner from Zendesk Sell's owner email to the Zoho User email for accurate assignment. Task notes attached to Tasks are handled as child records in sequence after the Task itself is created in Zoho.
Zendesk Sell
Notes
Zoho CRM
Notes
1:1Notes are free-text records attached to Contacts, Deals, Leads, or Companies in Zendesk Sell. We migrate Notes with their parent reference intact using Zoho's Related To field. Note body preserves rich text formatting where present in the Zendesk Sell export. Parent record resolution happens at migration time by matching the Zendesk Sell record ID to the newly created Zoho record.
Zendesk Sell
Call Records
Zoho CRM
Calls
1:1Call logs, call outcomes, and call duration data migrate to Zoho CRM Calls (a sub-type of Activities). Call recording audio files require separate file transfer to Zoho WorkDrive storage and are linked via URL reference. Call disposition maps to the Zoho Call Outcome picklist. Duration and timestamp migrate to Call Duration and Activity Date fields respectively.
Zendesk Sell
Tags
Zoho CRM
Tags
1:1Tags applied to Contacts, Deals, and Leads in Zendesk Sell migrate to Zoho CRM Tags. Zoho stores tags as comma-separated values on the Tagging subform of each record. We note that Zoho's tag-based filtering behaves differently from Zendesk Sell's tag model; the customer admin may need to adjust segmentation logic after migration.
Zendesk Sell
Custom Fields
Zoho CRM
Custom Fields
1:1Sell custom fields on Leads, Contacts, Deals, and Companies map to Zoho CRM custom fields. We resolve the numeric custom field ID and custom field key during scoping, create matching fields in Zoho (with appropriate field types: text, picklist, date, number, checkbox), and map values during import. Custom field dependencies and picklist value sets are configured before data migration begins.
Zendesk Sell
Users
Zoho CRM
Users
1:1Zendesk Sell Users (sales reps, admins) export with email, role, and territory. We map Users to Zoho CRM Users by email match. Territory assignments from Zendesk Sell are noted for reconfiguration in Zoho CRM's territory management module. Any Zendesk Sell User without a matching Zoho User goes to a reconciliation queue for admin provisioning before record import.

Pair-specific challenges
Migration approach
Discovery and sunset-timeline scoping
We audit the Zendesk Sell account with a focus on the August 31, 2027 deadline, assessing record volume across Leads, Contacts, Accounts, Deals, Tasks, Notes, and any custom objects. We identify active Sequences, workflow rules, and pipeline configurations to scope what migrates versus what requires rebuild. The discovery output is a written migration scope document with a recommended start date targeting at least 9 months before the sunset date, and a Zoho CRM edition recommendation (Standard, Professional, or Enterprise) based on the customer's automation and reporting requirements.
Zoho CRM schema configuration
We pre-create the Zoho CRM schema including custom fields (matched to Zendesk Sell custom field keys), pipeline and stage definitions (matching Zendesk Sell pipeline names, stage names, and ordinal positions), user roles, and territory assignments. This phase runs in parallel with Zendesk Sell data extraction. We configure duplicate detection rules, picklist value sets, and required-field behavior before any data is written to the destination.
Data extraction and cleaning from Zendesk Sell
We export Zendesk Sell data via the Sell Core API in batched requests with rate-limit handling (36,000 requests per hour cap). Custom field IDs are resolved to field keys during extraction. Data cleaning runs in parallel: duplicates are flagged, phone and date formats are standardized, and incomplete records are annotated for customer review. We produce a data-cleaning report before import begins.
Sandbox migration and reconciliation
We run a full migration into a Zoho CRM sandbox environment using production-like data volume. The customer's Zoho administrator reconciles record counts (Leads in, Contacts in, Accounts in, Deals in, Tasks in), spot-checks 25-50 records against the Zendesk Sell source, and validates that pipeline assignments and stage history are preserved. Any mapping corrections happen in sandbox before production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Accounts (from Zendesk Sell Companies), Leads, Contacts (with AccountId resolved from the Accounts phase), Deals (with pipeline, stage, and Contact-Account lookups resolved), Tasks and Activities, Notes (with parent record references resolved at migration time), Tags, and Call Records. Each phase emits a row-count reconciliation report before the next phase begins. We handle the Zendesk Sell job queue limit of 30 concurrent background jobs by monitoring the zendesk-ratelimit-inflight-jobs header and throttling batch submissions accordingly during extraction.
Cutover, validation, and automation rebuild handoff
We freeze Zendesk Sell writes during cutover, run a final delta migration of any records modified during the migration window, then enable Zoho CRM as the system of record. We deliver the Sequence inventory, workflow rule inventory, and Line Items documentation to the customer's Zoho administrator. We support a one-week hypercare window where we resolve reconciliation issues raised by the sales team. We do not rebuild Zendesk Sell workflows or sequences in Zoho Blueprint inside the migration scope; that is documented for the customer's admin to rebuild or a separate Zoho consulting engagement.
