Overview
Migrating from Glaze CRM to Twenty CRM is a niche, high-touch project. Glaze CRM does not publish API documentation, so there is no programmatic way to pull data without requesting a custom export through Softuvo Solutions, their vendor. That data extract alone can require 1-2 weeks of lead time before migration work begins. We then build a custom field inventory from a sample Glaze CRM export, inferring field types and validating against whatever non-standard schema the customer's white-label instance uses. Twenty CRM's flexible data model accepts Contacts, Companies, Opportunities, and Custom Fields as standard objects, but its schema is still evolving; version updates can affect how custom field data is stored. We sequence parent records (Companies) before child records (Contacts, Deals), use Twenty's REST API for import with rate-limit handling, and deliver a written pipeline and automation inventory for your admin to rebuild post-migration.
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 Glaze CRM object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Glaze CRM
Contact
Twenty CRM
Person
1:1Glaze CRM Contact records map to Twenty CRM Person objects. Standard fields (name, email, phone, company association) map directly. Glaze CRM's custom contact fields require type inference from a sample export — multi-select fields must be identified and remapped to Twenty's multi-select or tag structure. We sequence Person import after Company so that the workspaceId lookup resolves at insert time.
Glaze CRM
Company
Twenty CRM
Company
1:1Glaze CRM Company records map directly to Twenty CRM Company objects. Address data, industry tags, and related contacts transfer with field-level mapping. Glaze CRM Companies are the parent of Contacts and Deals, so we import Companies first in every migration phase. The company domain from Glaze CRM's website field maps to the domain field in Twenty.
Glaze CRM
Deal
Twenty CRM
Opportunity
1:1Glaze CRM Deal records map to Twenty CRM Opportunity objects. Deal name, amount, stage, and associated company or contact transfer. Pipeline stages are organizational-level in Glaze CRM and must be reconciled against Twenty's opportunity stage configuration before migration. We document existing Glaze CRM stage names and probabilities for the customer's admin to configure in Twenty's settings.
Glaze CRM
Lead
Twenty CRM
Person (Lead context)
1:1Glaze CRM Lead records — which are separate from Contacts in Glaze CRM — map to Twenty CRM Person records flagged as leads. Lead source, status, and owner assignment transfer to Twenty's person fields. We preserve the Glaze CRM lead status in a custom field for audit. If Twenty's data model uses Persons for both leads and contacts, we flag this during scoping.
Glaze CRM
Pipeline
Twenty CRM
Opportunity Stage Configuration
lossyGlaze CRM pipeline and stage configurations are organizational-level settings. We document every stage name, probability, and pipeline assignment from the source instance and deliver this as a configuration guide for Twenty's admin to implement. Pipeline structures do not migrate as configuration code — the rebuild is in scope for the customer's team.
Glaze CRM
Task
Twenty CRM
Task
1:1Glaze CRM Task records (subject, due date, assignee, status, linked entity) map to Twenty CRM Task objects. Completed vs. open status flags transfer. Task associations to Contacts, Deals, or Companies are remapped using the resolved Twenty record IDs from the parent import phases.
Glaze CRM
Custom Fields (Contacts, Companies, Deals)
Twenty CRM
Custom Fields (Person, Company, Opportunity)
lossyGlaze CRM custom fields on any object require a custom field inventory built from a sample export. Multi-select fields need special handling — we identify the delimiter used in Glaze CRM and map to Twenty's multi-select or tag structure. We pre-create all custom fields in Twenty's schema before any data import begins.
Glaze CRM
User / Owner
Twenty CRM
Workspace User
1:1Glaze CRM Users who own records map to Twenty CRM workspace users resolved by email address match. Inactive Glaze CRM users with no record assignments can be excluded. Active users without a matching Twenty account go to a reconciliation queue for the customer's admin to provision before the Opportunity and Task import phases begin.
Glaze CRM
Tag / Label
Twenty CRM
Tag
1:1Glaze CRM tags stored on Contacts, Companies, or Deals migrate as flat string arrays applied to the corresponding Twenty records. Tags do not carry their own metadata. We deduplicate tags at transform time to avoid inflating the target tag list.
Glaze CRM
Document (metadata only)
Twenty CRM
Attachment (metadata)
lossyGlaze CRM document attachments do not expose a documented file export API. We migrate document metadata — filename, upload date, linked record — as structured reference records in Twenty. The actual file binaries must be re-uploaded manually or through a separate file transfer arranged with the customer.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Glaze CRM gotchas
No public API schema means no automated export
White-label deployments create non-standard instance configurations
Custom field types are not documented in public-facing materials
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Export initiation and schema discovery
We begin by working with the customer to request a full data export from Glaze CRM through Softuvo Solutions. While awaiting the export, we ask the customer to provide a representative sample record set (10-20 records across Contacts, Companies, Deals, and Leads) with all custom fields visible. We use this sample to infer field types, identify multi-select delimiters, and document the custom field inventory. We also collect the Glaze CRM pipeline stage names, user list, and any automation or workflow documentation the customer can provide.
Schema design and field mapping
We design the destination schema in Twenty CRM based on the schema discovery output. This includes creating custom fields on Person, Company, and Opportunity objects, mapping Glaze CRM stage names to Twenty opportunity stage values, and configuring the workspace. We produce a written field mapping spreadsheet that the customer reviews and approves before any data is moved. White-label-specific fields that have no Twenty equivalent are flagged for the customer to decide whether to carry forward or drop.
Sandbox migration and reconciliation
We run a full migration into a Twenty CRM sandbox environment using the production-like data volume from the Glaze CRM export. The customer's team reconciles record counts, spot-checks 20-30 random records against the source export, and verifies that the Glaze CRM pipeline stages map correctly to Twenty opportunity stages. Any mapping corrections happen here. This step validates that the parent-record sequencing (Companies before Contacts, Contacts before Activities) resolves correctly.
Owner and user provisioning reconciliation
We extract every distinct Glaze CRM user referenced as an owner on any record and match by email against the Twenty CRM workspace user list. Any Glaze CRM owner without a matching Twenty user goes to a reconciliation queue. The customer's admin provisions the missing users before the production migration begins. Migration cannot proceed past this step because owner lookups must be resolved for Opportunity and Task inserts.
Production migration in dependency order
We run the production migration in record-dependency order: Companies (first, as parent), Persons (from Contacts and Leads, with workspaceId resolved), Opportunities (with companyId and personId resolved), Tasks, Tags, and custom field data. Each phase emits a row-count reconciliation report before the next phase begins. We use Twenty's REST API with rate-limit handling and batch chunking for large record sets.
Cutover, validation, and automation handoff
We freeze writes to Glaze CRM during the cutover window, run a final delta migration of any records modified during the migration period, then enable Twenty CRM as the system of record. We deliver a written inventory of every Glaze CRM pipeline configuration, email template, and automation requiring rebuild in Twenty CRM. We support a one-week hypercare window for reconciliation issues. We do not rebuild Glaze CRM workflows or automations in Twenty CRM — that work is in scope for the customer's admin or a Twenty implementation partner.
