Overview
Moving from Corteza CRM to Freshsales is a shift from a self-hosted, open-source model to a vendor-backed SaaS CRM with AI-powered insights, lead scoring, and integrated phone and email. Corteza organizes CRM content into namespaces with a module-based data model that supports custom objects and low-code field configuration, but namespace export can stall if any page references a deleted module, and standard CRM workflows including lead conversion automation buttons have been documented as broken after system restore or upgrade events. We audit orphaned page references before export, capture workflow definitions during discovery so they can be re-deployed post-migration, and resolve the Freshsales lead-conversion merge behavior (where duplicate emails are collapsed during classic account migration) upfront. We do not migrate workflows, automations, or sequences as code; we deliver a written inventory of these for the customer's admin to rebuild in Freshsales.
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 Corteza CRM object lands in Freshsales, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Corteza CRM
Lead
Freshsales
Lead
1:1Corteza Lead records map to Freshsales Lead with standard fields (first name, last name, email, phone, rating, status) migrated directly. Corteza's lead conversion workflow creates Accounts, Contacts, and Opportunities on conversion; Freshsales converts Leads into Accounts, Contacts, and Deals with configurable field mapping via Admin Settings > Leads > Field mapping. We preserve the original Corteza lead status and any custom lead fields as Freshsales custom fields. Note: during classic Freshsales account migration, Leads with duplicate email addresses are automatically merged; we flag this behavior and run deduplication before migration to prevent unintended record collapse.
Corteza CRM
Account
Freshsales
Account
1:1Corteza Account records map to Freshsales Account with company name, industry, address, and social media fields migrated directly. The account name becomes the Freshsales Account Name and serves as the dedupe key. If Corteza stores a website domain on the Account, it migrates to the Freshsales Website field. We preserve the account-industry classification for segmentation.
Corteza CRM
Contact
Freshsales
Contact
1:1Corteza Contact records map to Freshsales Contact with first name, last name, email, phone, and job title migrated directly. The contact-account relationship (parent Account link) is resolved by matching the Corteza Account Name or Account ID to the Freshsales Account record created earlier in the migration sequence. We validate that every Contact has a resolved AccountId before insert to avoid orphaned contacts.
Corteza CRM
Opportunity
Freshsales
Deal
1:1Corteza Opportunity records map to Freshsales Deal with stage, amount, probability, and close date migrated directly. The Corteza opportunity.accountID maps to the Freshsales AccountId lookup, and opportunity.ownerID resolves via email match to the Freshsales User. Deal stage values are mapped to Freshsales Deal stage values configured in Admin Settings. Probability and close date migrate as custom fields if the customer's reporting depends on them.
Corteza CRM
Campaign
Freshsales
Campaign
1:1Corteza Campaign records map to Freshsales Campaign with campaign name, type, status, and start/end dates. CampaignMember records linking Contacts and Leads to the Campaign migrate as Freshsales Campaign Members with Status (responded, sent, opted out). Activity history on campaigns (sent emails, opened tracking events) does not migrate as Freshsales campaign reporting is built from Freshsales' own email tracking rather than historical imports.
Corteza CRM
Case
Freshsales
Case
1:1Corteza Case records map to Freshsales Case with status, priority, origin, and resolution fields. Case-account and case-contact relationships are preserved by resolving the Account and Contact lookups at migration time. If the destination Freshsales account is on the Growth plan without a dedicated Service Cloud license, Cases may be handled as custom Deal or Task records; we confirm the plan tier during scoping.
Corteza CRM
Task
Freshsales
Task
1:1Corteza Task records migrate to Freshsales Task with status, due date, subject, description, and assignee preserved. Assignee resolution is by email match to Freshsales User. Tasks related to Leads, Accounts, Contacts, or Deals carry the corresponding WhatId or WhoId lookup. Standalone tasks without a parent record migrate with no lookup reference.
Corteza CRM
Event
Freshsales
Task (Event type)
1:1Corteza Event records (meetings, calls) migrate to Freshsales Task with TaskSubtype or custom event type field capturing the activity type. Start datetime, duration, and location migrate as custom fields on the Task. Attendee references are stored as a text field listing the resolved Contact or Lead names because Freshsales Tasks do not have an EventRelation equivalent for attendee tracking.
Corteza CRM
Custom Module
Freshsales
Custom Object or Custom Fields
lossyCorteza's low-code module builder can produce entirely custom modules with non-standard field types and validation rules. We pre-create the corresponding custom fields in Freshsales under the appropriate standard object (Lead, Contact, Account, or Deal) during the schema design phase. Custom modules that require standalone object behavior require Freshsales Enterprise ($69/user/mo) for custom objects; we confirm the destination plan tier and advise on upgrade if needed before migration begins.
Corteza CRM
Product
Freshsales
Product
1:1Corteza Product records with pricing information stored in PricebookEntry migrate to Freshsales Product. Product name, SKU, and unit price migrate directly. If the customer uses quote generation, we migrate the product catalog and price list so that Deals can reference products at migration time.

Migration approach
Discovery and namespace integrity audit
We audit the source Corteza CRM instance across all modules (standard and custom), custom field configurations, namespace structure, and workflow definitions. We specifically audit for orphaned page references that will block namespace export and flag them for cleanup. We identify all active workflow definitions and their trigger conditions so they can be inventoried for rebuild in Freshsales. We extract record counts per object and assess data quality (duplicates, blank required fields, missing owner references) to size the migration and identify any pre-migration data cleansing needed.
Freshsales schema design and plan confirmation
We design the destination schema in Freshsales: creating custom fields under Leads, Contacts, Accounts, and Deals to receive Corteza custom module fields; confirming that the destination plan tier supports the required object types (custom objects require Enterprise at $69/user/mo); and configuring the lead conversion field mapping in Admin Settings so that Corteza lead fields map to the correct Freshsales target fields before any Lead records are imported. Schema design is validated in a Freshsales sandbox or trial account before production migration begins.
Sandbox migration and reconciliation
We run a full migration into a Freshsales trial or sandbox environment using a representative data sample (typically 10-20% of total record volume). The customer's admin reconciles record counts and spot-checks 20-40 records field by field against the Corteza source. Any missing mappings, incorrect field type assignments, or parent-record resolution failures are corrected here. Freshsales' built-in CRM Migration tool can be used as a secondary comparison path if the customer has both options available. This step validates the migration path before production data moves.
Data extraction and pre-migration dedup
We extract all records from Corteza via its JSON API, run a deduplication pass on email addresses across Leads and Contacts to prevent the Freshsales duplicate-merge behavior from collapsing records, and resolve any missing owner references by mapping Corteza user emails to Freshsales User emails. Custom module records are extracted last because they may have dependencies on standard objects already migrated. We generate a pre-migration record count report for each object to serve as the baseline for post-migration reconciliation.
Production migration in dependency order
We run production migration in record-dependency order: Accounts first (from Corteza Accounts), then Contacts with AccountId resolved, then Leads with their field mapping configured, then Deals with AccountId and OwnerId resolved, then Cases, Tasks, Events, Campaigns, and Products. Each phase emits a row-count reconciliation report before the next phase begins. We use Freshsales' CSV import and API endpoints with batch chunking and backoff on rate-limit responses. Custom module records import last.
Cutover, validation, and workflow inventory handoff
We freeze Corteza writes during cutover, run a final delta migration of any records modified during the migration window, then enable Freshsales as the system of record. We deliver a written inventory of every active Corteza workflow with its trigger, conditions, actions, and a recommended Freshsales workflow equivalent (or manual process note where Freshsales does not support the equivalent action). We do not rebuild Corteza workflows as Freshsales automations inside the migration scope; that is a separate engagement or an internal admin task. We support a 72-hour hypercare window for reconciliation issues raised by the customer's team.
