Overview
Optimiser CRM to Zoho CRM is a migration from a platform with no public API and instance-specific custom fields to one with a documented Data Migration Wizard and per-edition field limits. The primary technical challenge is enumerating every active Optimiser field during scoping, because there is no reference schema — each instance defines its own custom property set. We solve this with a trial export that inventories all populated fields before we design the Zoho destination layout. Pipeline stages are configurable in Optimiser and must be explicitly mapped to Zoho Sales Stages during import. Automation rules (assignment rules, follow-up triggers) built in Optimiser do not export in machine-readable form; we deliver a written rebuild checklist mapped to Zoho Workflows and Blueprints. Activity history (calls, emails, meetings, notes) migrates via Zoho's CSV-based import with migration IDs linking each activity to its parent Contact, Deal, or Company record.

Object mapping
Each row shows how a Optimiser 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.
Optimiser CRM
Contact
Zoho CRM
Contact
1:1Optimiser Contact records map to Zoho CRM Contacts with standard fields (Full Name, Email, Phone, Mailing Address). Optimiser custom fields on Contacts are enumerated during the pre-migration trial export and created as equivalent Zoho custom fields before import. Email serves as the dedupe key during Zoho import to prevent duplicate Contact creation. Zoho Professional or higher is required for custom fields on Contacts; the free edition does not support them.
Optimiser CRM
Company
Zoho CRM
Account
1:1Optimiser Company records map to Zoho CRM Accounts. Company Name maps to Account Name as the primary display field; website domain maps to Website. Account is created before Contact import so that the Account-Contact lookup relationship is satisfied at the moment of Contact insert. Custom properties on Optimiser Companies are inventoried and mapped to Zoho custom fields on Account.
Optimiser CRM
Deal
Zoho CRM
Deal
1:1Optimiser Deals map to Zoho CRM Deals with Stage, Amount, Expected Close Date, and Owner preserved. Pipeline stage names from Optimiser are configurable per instance, so we extract the full stage list during scoping and apply a stage-mapping table to Zoho Sales Stages before migration. Any Optimiser stage with zero records is flagged for omission to avoid creating empty stages in Zoho.
Optimiser CRM
Lead
Zoho CRM
Lead
1:1Optimiser Lead records map to Zoho CRM Leads. Lead status, source, and any scoring fields migrate to corresponding Zoho custom fields. If the customer elects to treat all Leads as Contacts (for example, if Optimiser was used without a strict Lead qualification gate), we apply a bulk Lead-to-Contact convert strategy in Zoho after import, subject to customer approval during scoping.
Optimiser CRM
Activity (Call, Email, Meeting, Note)
Zoho CRM
Task, Event, Note
1:manyOptimiser activities export as a unified activity log. We split these into Zoho Task records for calls and to-dos, Event records for meetings, and Note records for free-text notes. Each activity is associated to its parent Contact, Account, or Deal using migration IDs that Zoho's Data Migration Wizard uses to resolve cross-module relationships. Activities are imported in chronological order by the original Optimiser timestamp.
Optimiser CRM
Custom Field
Zoho CRM
Custom Field
lossyEvery populated Optimiser custom field on Contacts, Companies, Deals, and Leads is enumerated during the trial export phase. We create equivalent Zoho custom fields (matching field type where possible: text, number, picklist, date, checkbox, etc.) before data import begins. Fields with zero data in Optimiser are excluded to avoid creating dead columns in Zoho. Custom fields are not available in Zoho's free edition; Standard edition or above is required.
Optimiser CRM
User / Owner
Zoho CRM
User
1:1Optimiser user records (name, email, role) map to Zoho CRM Users. We resolve Optimiser owners by email match against the Zoho destination User table. Any Optimiser owner without a matching Zoho User is held in a reconciliation queue for the customer's admin to provision before record import resumes. Active vs inactive status is preserved via a custom field if the customer needs it for reporting.
Optimiser CRM
Tag / Label
Zoho CRM
Tag
lossyOptimiser tags applied to Contacts or Deals export as label values. We migrate tags as-is and create matching Tag sets in Zoho CRM. Zoho Tags are created at the module level (Contact Tags, Account Tags, Deal Tags), and we map the Optimiser tag key-value pairs to the corresponding Zoho tag name. If Optimiser uses a tag taxonomy that exceeds Zoho's tag limit per record, we flag it for the customer's admin to decide on consolidation.
Optimiser CRM
Pipeline Stage
Zoho CRM
Sales Stage
lossyOptimiser allows configurable pipeline stages per deal type. We extract the complete stage list from the customer's instance during scoping and map each Optimiser stage to a Zoho Sales Stage. Stage probability percentages are mapped from Optimiser to Zoho where available. Zoho's Data Migration Wizard allows stage mapping during import, and we configure the mapping table before migration begins.
Optimiser CRM
Project
Zoho CRM
Custom Module
1:1Optimiser's project management module may coexist alongside CRM objects in some instances. If project records are in scope, we create a Zoho Custom Module named Projects (or the equivalent name) and migrate project records as a secondary pass after Deals and Contacts are fully imported. Custom modules in Zoho require Professional tier or above. Projects are mapped last because they may have lookup dependencies on Account and Contact records.

Pair-specific challenges
Migration approach
Discovery and Optimiser field inventory
We run a trial export from Optimiser CRM to enumerate every populated field across Contacts, Companies, Deals, Leads, and Activities. We also extract pipeline stage names, tag sets, owner list, and any custom object records in scope. This inventory defines the full schema surface we must recreate in Zoho. We pair this with a Zoho edition check to confirm whether custom fields, lookup fields, and custom modules are available at the target tier. The discovery output is a written scope document with the enumerated field list, pipeline stage mapping table, and Zoho edition recommendation.
Zoho schema provisioning and stage mapping
We create the Zoho CRM destination schema: custom fields on Contacts, Accounts, Deals, and Leads (matching the enumerated Optimiser field types), Sales Stages with probabilities mapped from Optimiser's stage list, and any custom modules required for Projects. Schema is built in a Zoho Sandbox or staging org first. We configure field-level security and page layouts per module before any data is inserted. If the target Zoho edition is Standard or Free, we flag every Optimiser custom field that cannot be created and work with the customer to drop or consolidate before migration.
Optimiser data extraction and preparation
We run the full CSV export sequence from Optimiser CRM, automating pagination across multiple export sessions to ensure complete coverage. We parse the exported files, apply the field-mapping transform (Optimiser field names to Zoho field API names), standardize date formats and phone number formatting, validate email addresses, and flag duplicates using Zoho's dedupe rules. Any attachments referenced in Optimiser are downloaded to a staging file store for re-upload to Zoho during the import phase.
Owner reconciliation and user provisioning
We extract every distinct Optimiser owner referenced on Contacts, Companies, Deals, and Activities and match by email against the Zoho destination User table. Any Optimiser owner without a matching Zoho User is added to a reconciliation queue. The customer's Zoho admin provisions the missing Users (active or inactive depending on whether the original Optimiser user is still active in the business). Migration cannot proceed past record insert because OwnerId references are required on Zoho's standard objects.
Production migration in dependency order
We run production migration in record-dependency order: Accounts (from Optimiser Companies), Contacts (with AccountId resolved), Leads, Deals (with AccountId, OwnerId, and Stage resolved), Activities (Tasks, Events, Notes via CSV import with migration IDs linking to parent records), and Custom Modules (Projects last, because they may have lookups to Account). Each phase emits a row-count reconciliation report before the next phase begins. Any records rejected by Zoho's validation rules are logged, corrected, and retried in a subsequent pass.
Cutover, validation, and automation rebuild handoff
We freeze Optimiser writes during cutover and run a final delta migration of any records modified during the migration window. We validate a statistical sample of migrated records against the Optimiser source data (targeting 25-50 records per module) before declaring migration complete. We deliver the automation rebuild checklist for Optimiser Workflows mapped to Zoho Workflow and Blueprint equivalents. We do not rebuild automations inside the migration scope; that work belongs to the customer's Zoho admin or a Zoho implementation partner. A one-week hypercare window covers reconciliation issues raised during the first days of Zoho production use.
