Overview
Moving from Axelor CRM to Mailchimp is a deliberate scope reduction, not a lateral move. Axelor is a full ERP+CRM+BPM platform with Lead-to-Third-Party-to-Opportunity pipeline tracking, BPM workflow logic, and J2EE-configured custom objects. Mailchimp is an email marketing platform with contact management, audience segmentation, and Customer Journey automations. We export Axelor Third Parties, Contacts, and Leads via the AppLoader mechanism and map them into Mailchimp Members, preserving address fields, phone numbers, and custom properties as Mailchimp merge fields. Agency and lead-routing assignments convert to Mailchimp Tags. Opportunities, BPM workflows, custom Studio objects, and user permission schemas do not migrate because Mailchimp has no equivalent object model. We deliver a written automation inventory for rebuilding Customer Journeys in Mailchimp and a custom-field schema for any Axelor Studio objects that require post-migration reconstruction in the destination.
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 Axelor CRM object lands in Mailchimp, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Axelor CRM
Third Party (Customer/Prospect)
Mailchimp
Member
1:1Axelor Third Parties map to Mailchimp Members within an Audience. The Third Party name maps to the Member's Full Name field; email maps to email_address; address fields map to Mailchimp's address merge fields (ADDR1, CITY, STATE, ZIP, COUNTRY). We use email as the dedupe key during import. Third Party type (customer vs prospect) is preserved as a custom merge field or as a Tag for segmentation.
Axelor CRM
Contact
Mailchimp
Member
1:1Axelor Contact records linked to a parent Third Party map to Mailchimp Members with the contact's email, first name, last name, and phone. The parent Third Party relationship is resolved by matching the Third Party email as the organization identifier in Mailchimp. If no matching Third Party exists in the source export, we create the Contact as a standalone Member.
Axelor CRM
Lead
Mailchimp
Member (segmented)
1:1Axelor Leads map to Mailchimp Members within the target Audience. Lead status (New, Assigned, Qualified, Converted) maps to a custom merge field or a Tag for segmentation. Converted Leads (those converted to Third Parties in Axelor) are reconciled against the Third Party export and imported as Members only once, avoiding duplicate records.
Axelor CRM
Agency
Mailchimp
Tag
lossyAxelor Agency records have no direct Mailchimp equivalent. We export the Agency list and create each Agency as a Mailchimp Tag. The Lead-to-Agency many-to-many junction export is resolved by applying multiple Tags to each Member based on their agency assignments. The customer selects the naming convention (Agency name as tag, numeric code as tag) during scoping.
Axelor CRM
Lead Agency Assignment
Mailchimp
Tag Assignment
1:1The many-to-many relationship between Leads and Agencies is resolved by exporting the junction records and applying the corresponding Tags to each Member at migration time. If a Lead is assigned to Agency A and Agency B, both Tags are applied to that Member's profile in Mailchimp.
Axelor CRM
Note (on Third Party/Contact)
Mailchimp
Note
1:1Axelor notes linked to Third Parties and Contacts migrate as Mailchimp Member notes. We preserve the original note text, the note author (extracted from the Axelor user record), and the creation timestamp. Notes are imported via the Mailchimp Members Notes endpoint after the Member records are created.
Axelor CRM
Recurrent Revenue Fields (Opportunity)
Mailchimp
Custom Merge Field
lossyThe recurrent revenue amount and period fields on Axelor Opportunities exist only when the 'Manage recurrent revenue on opportunities' CRM setting is activated. We detect this configuration during scoping and, if present, create custom merge fields in Mailchimp to carry the recurring amount and period values. These fields serve as reference data only since Mailchimp has no opportunity tracking.
Axelor CRM
Opportunity
Mailchimp
None
1:1Axelor Opportunities track sales pipeline with stages, expected amounts, and revenue dates. Mailchimp has no opportunity or deal tracking object. Opportunities are excluded from migration scope. We document the pipeline stages, stage probabilities, and revenue figures in a written summary so the customer's admin can reference them during planning or when selecting a downstream CRM if opportunity tracking is required.
Axelor CRM
Custom Object (Studio)
Mailchimp
Custom Merge Field or Tag
lossyAxelor Studio custom objects defined in XML and compiled as JPA models require schema inspection during scoping. If the custom object has a direct email-address field, we create a custom merge field in Mailchimp to carry the data. If it does not have an email field, we flag it as a non-migratable reference object and document its schema for manual entry or a separate tagging campaign.
Axelor CRM
User/Owner
Mailchimp
None
1:1Axelor user records include roles, organizational structure, and access permissions. Mailchimp does not have a user management or permission model equivalent to Axelor's role-based access. User records are not migrated. We document the owner assignment on each Third Party, Contact, and Lead so the customer can assign Members to Mailchimp user accounts manually post-migration if team-based access control is needed.

Migration approach
Discovery and scoping
We audit the source Axelor instance by version (6.1.x through 6.5.x carry different schema), export a list of all Third Parties, Contacts, Leads, Agencies, custom Studio objects, and any configured recurrent revenue fields. We inspect the Opportunity XML schema to confirm whether recurrent revenue fields are present and detect any Studio custom object definitions. We confirm the target Mailchimp Audience (or create one during migration) and identify any existing contacts that may generate duplicates on import.
Schema inspection and field mapping
For each identified object, we generate a field-level map from Axelor XML field names to Mailchimp Member merge fields. We create any missing custom merge fields in the Mailchimp audience before migration begins. Agency records are assigned as Tags. The Lead-to-Agency junction export is processed to generate the tag application list. We flag any Axelor object with no email field as non-migratable for immediate customer acknowledgment.
Data extraction via AppLoader
We extract Third Parties, Contacts, and Leads from Axelor using the AppLoader export mechanism, supplemented by the REST API for records modified after the AppLoader snapshot. The export is performed in batches to avoid overwhelming the Axelor instance, and we monitor for connection failures given the undocumented rate limit. Extracted records are staged in a CSV format normalized for Mailchimp's batch import requirements.
Sandbox migration and reconciliation
We run a full migration into a test Mailchimp Audience using production-like record volume. The customer reconciles record counts (Third Parties in, Contacts in, Leads in), spot-checks field values against the Axelor source, and confirms that Tags are applied correctly for agency routing. Any field mapping corrections and any missing merge fields are added before the production migration begins.
Production migration
We run production migration in record order: Members first (from Third Parties, Contacts, and Leads), Notes second (linked to Members via the Mailchimp Notes API), Tags third (applied to Members based on agency and lead routing assignments), and custom merge field values last. Each phase emits a row-count report. We apply exponential backoff on any Mailchimp API 429 responses and retry failed records up to three times before surfacing them in the reconciliation report.
Cutover and automation handoff
We freeze writes to the Axelor instance during cutover, run a final delta migration of any records modified during the migration window, then mark Mailchimp as the system of record. We deliver the BPM workflow inventory document, the Opportunity pipeline summary, and the custom Studio object schema documentation to the customer's admin team for rebuild in Mailchimp Customer Journeys. We support a 48-hour hypercare window for reconciliation issues raised by the customer's team.
