Overview
Constructor CRM and Zoho CRM share the same core object model — Leads, Contacts, Accounts, Deals, Tasks, and Events exist in both platforms with similar names and purposes. The migration carries everything Constructor stores natively into Zoho's equivalent modules. The complexity lives in the details: Constructor's custom fields require Zoho custom fields to be pre-created before import; pick-list values (deal stages, lead sources, industry verticals) need explicit value-by-value mapping because Zoho stores pick-list labels rather than numeric IDs; and any multi-select fields must use Zoho's semicolon-delimited format or the import skips those records. FlitStack sequences the migration so parent records (Accounts) land before child records (Contacts) and deals, preserving all foreign-key relationships. We surface Constructor's workflows and automation rules as a structured export so your Zoho admin can rebuild them in Blueprint. The delta-pickup window captures any records modified during cutover so Zoho reflects Constructor's final state at go-live. Zoho's API rate limits vary by edition — Starter caps at 500 requests per minute versus Professional at 2,500 — which affects batch sizing during large migrations. FlitStack handles all of this under scoped read access on Constructor; your team keeps working in the source system throughout.

Object mapping
Each row shows how a Constructor 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.
Constructor
Lead
Zoho CRM
Lead
1:1Constructor leads migrate directly to Zoho Leads. Zoho Lead fields (Lead Status, Lead Source, Industry) map to equivalent Constructor pick-list values. Unconverted Constructor leads that are already associated with a company land as Zoho Leads — the Account link is preserved as a lookup field.
Constructor
Contact
Zoho CRM
Contact
1:1Constructor contacts map 1:1 to Zoho Contacts. The primary Account link (Constructor's company field) becomes Zoho's Account Name lookup. Contacts without a primary company are attached to a default placeholder Account so Zoho's required AccountId constraint is satisfied during import.
Constructor
Account
Zoho CRM
Account
1:1Constructor accounts migrate directly to Zoho Accounts, preserving fields such as name, website, phone, industry, ownership, and address. Parent‑child hierarchies map to Zoho's Account Hierarchy field, so parent accounts are imported first to build the tree. Multi‑account associations on a single contact collapse to a primary AccountId plus the Account Contact Relation secondary link, matching Zoho's 1:N‑to‑N:N model. All custom account fields transfer to Zoho custom fields after schema setup.
Constructor
Deal
Zoho CRM
Deal
1:1Constructor deals map to Zoho Deals directly. Constructor's pipeline and stage pair maps to Zoho's Pipeline and Stage pick-list values via explicit value-by-value mapping since Constructor stage names rarely match Zoho's default stage labels. Amount, close date, and owner transfer as-is.
Constructor
Task
Zoho CRM
Task
1:1Constructor call logs and to-do tasks migrate as Zoho Tasks with the Type field set to Call or Task respectively. Subject, Description, Status, and Priority carry over. Original Created Time and Assigned To timestamps are preserved; the Owner resolves by email match to Zoho users.
Constructor
Event
Zoho CRM
Event
1:1Constructor meetings and calendar events migrate as Zoho Events. Start DateTime and End DateTime transfer directly. All-day events use Zoho's All-Day Event flag. The WhatId field links the event to the parent Contact, Account, or Deal record using the ID preserved from Constructor's association.
Constructor
Note
Zoho CRM
Note
1:1Constructor notes migrate as Zoho Notes with Content (body text) and ParentId linking back to the related record. Rich-text formatting is preserved where the source format is HTML; plain-text notes import cleanly. Note titles default to a truncated excerpt of the note body if Constructor did not store a separate title field.
Constructor
Attachment
Zoho CRM
Attachments module
1:1Constructor file attachments are extracted from records, re-uploaded to Zoho's Attachments module, and linked back to the parent record via the Related To field. Individual file size is capped at 25MB in Zoho — files exceeding this limit are flagged before migration so your team can decide whether to host externally or split the attachment.
Constructor
Custom Object
Zoho CRM
Custom Module
1:1Constructor custom objects map 1:1 to Zoho Custom Modules. If the Constructor custom object name contains _C, Zoho's migration wizard auto-creates the module during import; otherwise the module is pre-created in Zoho before data lands. Custom-object relationships that are many-to-many in Constructor map to Zoho's linking modules or related-list lookups depending on the relationship cardinality.
Constructor
User / Owner
Zoho CRM
User
1:1Constructor owner IDs resolve to Zoho users by email address match. Unmatched owners are flagged before migration — your team either creates the Zoho user first or assigns those records to a fallback owner. This is a prerequisite step that must complete before any module migration runs because Zoho requires a valid OwnerId on all owned records.
Constructor
Workflow / Automation
Zoho CRM
Blueprint / Workflow Rules
1:1Constructor workflows and automation rules do not migrate. FlitStack exports your Constructor workflow definitions as a structured JSON document and a written description of each rule's trigger, condition, and action so your Zoho admin or implementation partner has a rebuild reference. Workflows must be manually reconstructed in Zoho Blueprint or Deluge after the data migration completes.
Constructor
Report / Dashboard
Zoho CRM
Report / Dashboard
1:1Constructor reports and dashboards are not migrated — the underlying data comes over but the report definitions, chart configurations, and scheduled delivery settings are destination-side configuration. FlitStack documents which records feed each Constructor report so the rebuilding admin knows which Zoho Reports or Analytics modules to rebuild and which Zoho custom fields the reports should reference.
Constructor
Integration / Connection
Zoho CRM
Integration / Connection
1:1Constructor's third-party integrations (Outlook sync, Gmail plugins, Zapier connections, accounting connectors) do not migrate. Each integration must be rebuilt in Zoho or reconnected to the new CRM using Zoho's connector library, Zoho Flow, or the same third-party middleware your team already uses. FlitStack lists every active integration found during discovery so none are forgotten at cutover.
Constructor
Constructor-specific tag or label
Zoho CRM
Custom field on Contact or Deal
1:1Constructor stores relationship labels and tags on contacts and deals that have no built-in Zoho equivalent. These migrate as custom pick-list or multi-select fields on the relevant module. You choose the field type in Zoho — single-select for simple tags or multi-select if Constructor stored multiple labels per record. The original Constructor label names are preserved as field values.
Constructor
Constructor's Last Modified timestamp
Zoho CRM
Custom field (Last_Modified_Source__c)
1:1Zoho's standard Last Modified Date reflects when the record was changed in Zoho, not when it was last updated in Constructor. We preserve Constructor's last-modified timestamp as a custom datetime field so reporting shows the original modification history. This is essential for teams whose SLA metrics or sales-cycle reporting depend on the source system's modification dates.

Migration approach
Discovery and source audit
FlitStack connects to Constructor via API using scoped read access and inventories all modules, field names, pick-list values, custom objects, and attachment volumes. We identify all active integrations, workflow definitions, and any records with missing required fields. The discovery output includes a record-count summary per module, a full field inventory with data types, and a list of pick-list values that need to be pre-created in Zoho before import. This phase establishes the migration scope and forms the basis of the fixed-price quote.
Zoho schema pre-configuration
Before any data moves, your Zoho admin creates the custom fields, pick-list values, and pipeline/stage configuration that the migration requires. FlitStack delivers a Zoho setup checklist specifying every field API name, pick-list value, and pipeline layout needed for the migration. Custom fields that do not exist in Zoho yet are flagged for creation; pick-list values that are missing from Zoho's field settings are listed with their Constructor values so your admin adds them before the import window opens. This step is a prerequisite — data cannot land cleanly without the destination schema ready.
Field mapping and deduplication rules
FlitStack builds a field-mapping spreadsheet that pairs every Constructor field to its Zoho equivalent, documents transformation logic for split fields and multi-select formats, and specifies value-mapping tables for pick-list fields. Deduplication rules are defined at this stage — by default, records are matched by email address on Contacts and Leads, and by company name on Accounts. You review and approve the mapping before any data extraction begins. Constructor's workflow definitions are exported as a structured reference document for the Zoho Blueprint rebuild phase.
Data export and cleansing
FlitStack extracts all modules from Constructor via API in parent-before-child sequence: Accounts first, then Contacts and Leads, then Deals, then Activities. Attachments are downloaded separately for re-upload to Zoho. During extraction, records with missing required fields are flagged and queued for cleansing decisions — either the missing data is sourced from a secondary Constructor export or a default value is applied per your approved rules. Duplicate records are identified and either merged or tagged with a custom duplicate flag field in Zoho. Date formats, phone number formats, and multi-select delimiters are normalized to Zoho's import requirements.
Test migration with field-level diff
A representative slice of records (typically 100–300 per module) migrates to a Zoho sandbox or scratch org first. FlitStack generates a field-level diff report comparing source values against destination values for every mapped field, flagging any field where the destination value does not match the source. You review the diff to confirm that pick-list value mapping, owner resolution, and custom field population are working as expected. No records are permanently migrated until you approve the test results. This step typically takes 1–2 days.
Full migration with delta pickup and go-live
The full dataset migrates to your production Zoho environment. A delta-pickup window of 24–48 hours runs concurrently — any records created or modified in Constructor during the migration window are captured and applied to Zoho after the initial load. FlitStack maintains an audit log of every record inserted, updated, or skipped during the migration. One-click rollback is available if post-migration reconciliation finds discrepancies. Once you confirm the Zoho data matches Constructor's final state, the migration is complete and your team is cleared to begin the Zoho workflow rebuild using the exported Constructor workflow definitions.
