Overview
Moving from Concord CRM to Zoho CRM is a shift from a self-hosted one-time-purchase model to a cloud SaaS subscription with per-user pricing. Concord CRM stores data as Contacts, Companies, Deals, Products, and Activities exportable via CSV or REST API; Zoho CRM uses Leads, Accounts, Contacts, Potentially-custom Deals modules, Tasks, Events, and Products with a standard module mapping that we configure before import. The primary migration challenge is Concord's API pagination cap at 100 records per page, which we handle with sequential page iteration and rate-limit monitoring, and the absence of any native Concord-to-Zoho migration connector in Zoho's Data Migration Wizard. We extract via Concord's REST API or CSV export, sequence Companies before Contacts to satisfy Zoho's Account-Contact lookup chain, map Concord's deal stages to Zoho Pipeline stage values, and reconstruct activity associations using Concord's linked resource type and ID fields. Workflows do not fire during data import in Concord CRM and must be manually rebuilt in Zoho's Workflow Rules builder; attachments stored in Concord's storage/app directory must be manually transferred via file system access. We deliver a written inventory of all active workflows, custom field configurations, and attachment files requiring manual action post-migration.

Object mapping
Each row shows how a Concord CRM 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.
Concord CRM
Company
Zoho CRM
Account
1:1Concord CRM Company records map directly to Zoho CRM Account. The Company must be exported and imported before Contact because Zoho Accounts are the parent record for Contacts via the Account Name lookup field. We extract the company_id, company_name, website, phone, address, and any custom fields from Concord's Companies endpoint or CSV export and map them to the corresponding Zoho Account fields. If the Concord Company has a primary contact flag, we carry that forward for Contact sequencing.
Concord CRM
Contact
Zoho CRM
Lead and Contact (split required)
1:manyConcord CRM Contacts do not distinguish between unqualified prospects and qualified buyers; Zoho CRM separates Leads (unqualified) from Contacts (qualified, attached to Accounts). We apply a split rule during scoping based on the customer's Concord CRM data: Contacts with no associated Deals and no sales activity history typically map to Zoho Lead; Contacts with active Deals or recent task/logged activities map to Zoho Contact attached to the corresponding Account. The original Concord contact_id is preserved in a custom field concord_original_id__c for reconciliation. If the customer has no lead-conversion process, all Concord Contacts can map directly to Zoho Contacts attached to Accounts.
Concord CRM
Deal
Zoho CRM
Potentially-custom module (Potentially-custom module or Deals)
1:1Concord CRM Deals map to Zoho CRM Potentially-custom module or standard Deals module depending on the customer's Zoho edition configuration. Concord deal fields (deal_name, amount, expected_close_date, stage, owner) map to Zoho Potentially-custom module or Deal Name, Amount, Closing Date, Stage, and Owner. Concord pipeline stages are exported as raw stage names or IDs and must be mapped to Zoho Pipeline stage values that we configure before import. We flag any Concord Deals without a valid associated Contact or Company for manual review before insertion.
Concord CRM
Deal Stage
Zoho CRM
Potentially-custom module Stage
lossyConcord CRM pipeline stages are stored as deal properties and export as stage names or IDs. We map each Concord stage to a Zoho Pipeline stage with a corresponding probability percentage. If the customer has multiple Concord pipelines, we create multiple Zoho Potentially-custom module or Potentially-custom module pipelines, each with its own stage sequence. Stage mapping is validated against the customer's Concord stage names during scoping.
Concord CRM
Product
Zoho CRM
Products
1:1Concord CRM Products (name, price, SKU, description) map directly to Zoho CRM Products. Products are independent of other objects in Concord and migrate straightforwardly. We map product_name to Product Name, price to Unit Price, sku to Product Code, and description to Description. Price book entries in Zoho are created during the migration to support Deal product line items if the customer uses product-linked Deals.
Concord CRM
Activity (calls, meetings, tasks)
Zoho CRM
Tasks and Events
1:1Concord CRM Activities (calls, meetings, tasks) export with type, date, notes, and linked resource ID. We reconstruct the association by resolving the linked resource type (Contact, Company, Deal) and ID to the migrated Zoho record's ID. Calls and general tasks map to Zoho Tasks with Task Type set to Call or Task respectively; meetings map to Zoho Events with Start Date Time, End Date Time, and Location preserved. Concord activity timestamps are preserved as Activity Date in Zoho for timeline ordering. Note: Concord CRM does not export email engagements as a distinct activity type; emails are typically stored as activity notes rather than structured records.
Concord CRM
Custom Fields
Zoho CRM
Custom Fields
1:1Concord CRM custom fields (boolean, date, select, text, number) export with the field UUID as the key in the request payload. We map these to Zoho CRM custom fields created in the respective module before migration. Zoho custom fields require paid edition access (not available in Free edition) and are subject to field limits per module per edition. We confirm the customer's Zoho edition during scoping and create all custom fields before any data import begins. Boolean fields from Concord map to Zoho Checkbox; date fields map to Zoho Date; select fields map to Zoho Picklist with matching values.
Concord CRM
Users
Zoho CRM
Users
1:1Concord CRM Users export via API with email, name, and role assignment. We resolve Concord users by email match against the Zoho CRM destination's User table. Owners referenced on Concord Deals and Contacts map to Zoho Owner by email. Any Concord user without a matching Zoho User goes to a reconciliation queue for the customer's admin to provision before record import resumes. Role permissions from Concord are documented but must be manually reconstructed in Zoho Profiles and Permission Sets.
Concord CRM
Workflows
Zoho CRM
Workflow Rules
lossyConcord CRM Workflows (trigger: Company/Contact/Deal created, Deal stage changed; action: Create Activity, Send Email, Trigger Webhook) do not execute during data import. We do not migrate workflows as code. We audit all active Concord CRM workflows during scoping, document the trigger conditions, actions, and intended logic, and deliver a written workflow inventory with recommended Zoho Workflow Rules equivalents. The customer's admin rebuilds these manually in Zoho's Workflow Rules builder post-migration. This is a manual scope item outside the data migration scope.
Concord CRM
Attachments
Zoho CRM
Attachments or Documents
1:1Concord CRM does not include a document attachment export feature in the standard export tool or API. Attachments stored in the application's storage/app directory must be manually extracted via file system access (FTP/SFTP) and transferred. We document the storage directory structure, list all attachment files with their associated record IDs, and provide the customer with a file-transfer playbook. Attachments are then manually reattached in Zoho CRM under the Documents module or linked via Zoho WorkDrive. This is a manual scope item outside the automated data migration scope.

Pair-specific challenges
Migration approach
Discovery and source audit
We audit the source Concord CRM installation across all modules: Contacts, Companies, Deals, Products, Activities, custom fields, and active workflows. We extract record counts per module, identify the Concord pipeline and stage names, list custom field UUIDs and types, and flag any attachments stored in the storage/app directory. We confirm the Concord export permission assignment and the customer's Zoho CRM edition. The discovery output is a written migration scope with module mapping, custom field inventory, workflow inventory, and an attachment file-transfer recommendation.
Data extraction sequencing and validation
We extract Concord CRM data in dependency order: Companies first (because Contacts reference company_id), then Contacts, then Deals, then Products, then Activities. Companies and Products export cleanly without foreign-key dependencies. Contacts are extracted with their company_id for Account resolution in Zoho. Deals are extracted with their associated contact_id and company_id for Potentially-custom module or Deal linking. Activities are extracted last with linked resource type and ID for parent-record resolution. We validate row counts against Concord's API response totals and CSV export totals before proceeding to the transform phase.
Transform and field mapping
We transform Concord export data to match Zoho's import format: Concord Companies become Zoho Accounts with account name, website, phone, and address fields; Concord Contacts become Zoho Leads or Contacts based on the split rule defined during scoping, with Concord company_id resolved to Zoho Account ID; Concord Deals become Zoho Potentially-custom module or Potentially-custom module records with stage mapped to the configured Zoho Pipeline stage; Concord Products become Zoho Products with price and SKU. Custom field values are mapped to Zoho custom fields created in the respective module. Concord activity types (call, meeting, task) are assigned to Zoho Task or Event with the linked resource ID resolved to the migrated Zoho record ID.
Zoho schema preparation
Before any data import, we configure the Zoho CRM destination: we create custom fields in each module matching the Concord custom field inventory; we configure Potentially-custom module or Pipelines with stage values matching the Concord pipeline stage names and probability percentages; we confirm Zoho edition capabilities (custom fields require paid edition); and we document Profile and Permission Set requirements for the migration user. If the customer has multiple Concord pipelines, we create multiple Zoho Potentially-custom module pipelines. Schema preparation is validated against the transform mapping document before import begins.
Production migration in dependency order
We run production migration in record-dependency order: Accounts (from Concord Companies), Products, Leads and Contacts (with AccountId resolved for Contacts), Potentially-custom module or Potentially-custom module Deals (with AccountId, OwnerId, and ContactId resolved), and Activities (Tasks and Events with WhoId and WhatId resolved to the migrated Zoho record IDs). Each phase emits a row-count reconciliation report before the next phase begins. We handle the Concord API pagination overhead with sequential page iteration and CSV export fallback for large datasets. Concord workflows and attachments are flagged as manual scope items and do not appear in the automated migration sequence.
Cutover, validation, and manual scope handoff
We freeze Concord CRM 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 validate record counts, spot-check 25-50 records per module against the Concord source, and confirm that parent-record lookups (Account on Contact, Account on Potentially-custom module or Deal, WhoId and WhatId on Tasks and Events) are correctly resolved. We deliver the workflow inventory document, the attachment file-transfer playbook, and the custom field mapping summary to the customer's admin team. We support a one-week hypercare window for reconciliation issues raised by the customer's team. Workflow rebuild, attachment re-upload, and Zoho Workflow Rules configuration are manual scope items outside the data migration engagement.
