Migrate from Rainbow CRM to Zoho CRM

Rainbow CRM Companies export as flat records with name, domain, address, and phone fields. We import them first into Zoho CRM Accounts to satisfy the AccountId lookup that Zoho requires on Contacts. The Company name becomes the Account Name, and the domain becomes the Website field for deduplication during contact import.

Contacts export cleanly from Rainbow CRM via CSV with standard fields (first name, last name, email, phone, address). We map these directly to Zoho CRM Contact fields. Lifecycle stage is not a native Rainbow CRM field and will not appear in exports; we flag this absence during schema inspection and note that Zoho's Lead Status or a custom picklist field can serve as a replacement segmentation axis if the customer requires it.

Deals export from Rainbow CRM with pipeline stage labels that use Rainbow's internal naming conventions. These stage names do not match Zoho CRM's default stage values. We present a stage mapping table during the scoping call showing each Rainbow stage and the proposed Zoho stage, and we apply the agreed mapping before the first import batch. Closed-won and closed-lost reasons from Rainbow custom fields map to Zoho Loss Reason and Won Reason fields if present in the export.

Rainbow CRM Leads export as a separate object from Contacts. Rainbow Leads may share email addresses with existing Rainbow Contacts, so we deduplicate at import time and flag duplicate email conflicts for customer review before writing records to Zoho. Lead source and lead status from Rainbow map to Zoho's Lead Source and Lead Status picklist fields where those values exist in the export.

Tasks export from Rainbow CRM as flat records without assignee IDs. We map task titles, due dates, and descriptions directly. Assignee resolution requires a cross-reference against Zoho CRM's User list by email address. Any task assigned to an email not matching an existing Zoho User goes to a reconciliation queue for the customer's admin to provision before the record import continues.

Activity history (calls, emails, meetings, notes) exports from Rainbow CRM in a denormalized format. We reconstruct activity threads and attach them to the correct Contact, Deal, or Account record during Zoho import. Calls and completed tasks map to Zoho Task with TaskSubtype preserved. Meetings map to Zoho Event with start and end times preserved. Notes attach via Zoho Notes or ContentDocumentLink depending on the export format.

Rainbow CRM exposes a subset of custom fields in its CSV export, but not all custom field types are included in the documented export format. We inspect the export schema during the discovery phase and flag any custom fields that do not appear. For high-value custom fields missing from the export, we coordinate a supplemental extraction or ask the customer to export those fields manually. Zoho CRM supports custom fields on all standard modules up to a maximum of 300 fields per module.

Rainbow CRM does not expose file attachments or document records through its documented export format. Any linked files stored in Rainbow CRM must be migrated separately via direct database access (where Rainbow provides it) or manual re-upload to Zoho CRM's file storage. We flag this gap in the scoping report and provide a manual attachment re-upload checklist for the customer's admin.

Rainbow CRM exports user records including name and email. We match Rainbow users by email against Zoho CRM's User table during scoping. Any Rainbow user without a matching Zoho User is held in a reconciliation queue; the customer's admin provisions missing Zoho users before record migration resumes, because OwnerId references are required on most standard Zoho objects.

Rainbow CRM pipeline definitions export with stage names but without stage order or probability values in the base export. We reconstruct the pipeline structure in Zoho CRM during the schema design phase, creating one Pipeline per Rainbow pipeline with stages ordered according to the customer's confirmed stage sequence. Stage probabilities are either provided by the customer or set to Zoho defaults for manual configuration after migration.
