Overview

What this migration involves

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.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Corteza CRM logo

Corteza CRM

What's pushing teams away

  • Enterprise support is unclear — despite Enterprise tier branding, there is no documented SLA or dedicated support channel, leaving self-hosted teams without recourse when issues arise.
  • Workflow stability after upgrades is inconsistent — lead conversion automation buttons have been documented as disabled after restore operations, requiring manual re-import of workflow definitions to fix.
  • The platform feels bare for production use — federation is marked experimental and disabled by default, and multiple standard CRM functions still require manual scripts or DB workarounds.
  • Self-hosting carries hidden operational cost — teams need DevOps capacity for deployment, backups, updates, and troubleshooting that SaaS CRMs absorb entirely.

Choosing

Freshsales logo

Freshsales

What's pulling them in

  • Lowest barrier to entry among major CRMs — the free tier supports up to 3 users and includes core CRM functionality before committing to per-seat pricing.
  • Built-in chat, email, and phone reduce reliance on third-party integrations for basic sales communication and contact management.
  • Freddy AI contact scoring and deal insights are included on Pro plans at a lower price than comparable HubSpot tiers.
  • Kanban pipeline views across Contacts, Accounts, and Deals provide visual deal management without requiring custom configuration.
  • Integration with the broader Freshworks ecosystem (Freshdesk, Freshchat, Freshservice) reduces tool sprawl for teams already using Freshworks.

Object mapping

How Corteza CRM objects map to Freshsales

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

maps to

Freshsales

Lead

1:1
Fully supported

Corteza 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

maps to

Freshsales

Account

1:1
Fully supported

Corteza 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

maps to

Freshsales

Contact

1:1
Fully supported

Corteza 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

maps to

Freshsales

Deal

1:1
Fully supported

Corteza 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

maps to

Freshsales

Campaign

1:1
Fully supported

Corteza 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

maps to

Freshsales

Case

1:1
Fully supported

Corteza 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

maps to

Freshsales

Task

1:1
Fully supported

Corteza 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

maps to

Freshsales

Task (Event type)

1:1
Fully supported

Corteza 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

maps to

Freshsales

Custom Object or Custom Fields

lossy
Fully supported

Corteza'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

maps to

Freshsales

Product

1:1
Fully supported

Corteza 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.

Pair-specific challenges

  • Namespace export fails on orphaned page references

    Corteza's namespace export path explicitly fails when any page in the namespace references a deleted module. This prevents a complete take-your-entire-CRM-and-move-it migration from completing. We audit the namespace for orphaned page references before attempting export, clean up the broken page-module links, and then proceed with the namespace package so the migration does not stall at the export step. This discovery phase adds scope that does not exist when migrating from platforms with a clean, well-documented export path.

  • Freshsales merges Leads with duplicate emails during classic migration

    When using Freshsales' built-in Classic Migration tool for free CRM accounts, Leads with duplicate email addresses are automatically merged on the destination side to eliminate duplication. For manual CSV-based imports, we run deduplication before migration to ensure no unintended merges occur. We flag this behavior during scoping and advise running the email dedup pass on the Corteza source data before any records move.

  • Corteza workflow definitions do not survive migration

    Corteza workflow definitions including lead conversion automation buttons are documented as broken after system restore or upgrade, and the namespace export explicitly excludes workflow references. This means there is no clean migration path for Corteza workflows that preserves button linkage. We capture workflow definitions during discovery so they can be re-built in Freshsales manually, but the automation itself does not transfer and requires the customer's admin to rebuild in Freshsales' workflow builder ($29/user/mo Advanced tier).

  • Corteza has no publicly documented API rate limits

    Corteza does not publish API rate limit quotas in its public documentation. For bulk migration operations, this means we cannot pre-configure rate-limit-aware throttling without performing discovery requests against the specific instance. We start with conservative request pacing and monitor for HTTP 429 responses to dynamically adjust throughput. This discovery overhead can extend the extraction phase compared to platforms with documented rate limits.

  • Freshsales lead field mapping must be configured before conversion

    Freshsales' lead conversion mapping (how Corteza lead fields map to Freshsales Contact, Account, and Deal fields) must be configured in Admin Settings before any leads are converted. If lead custom fields exist in Corteza and the corresponding target fields do not exist in Freshsales, the data is lost during conversion. We confirm all target fields are created in Freshsales before the Lead migration phase begins, using the field mapping dropdown in Admin Settings > Leads module.

Migration approach

Six steps for a successful Corteza CRM to Freshsales data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Most migrations land between three and five weeks for accounts under 15,000 total records and no custom modules. Migrations with custom modules, large engagement histories (over 200,000 activity records), or namespace export failures requiring orphaned page cleanup move to six to ten weeks because of Corteza discovery overhead, Freshsales field-mapping configuration per object, and the Freshsales lead-conversion field mapping setup that must be completed before Leads are imported.
