Overview
Moving from Nimble CRM to Twenty CRM is a structural transition that trades Nimble's social-first inbox integration and flat per-seat pricing for Twenty's open-source self-hosted model, unlimited storage, and granular opportunity tracking. Nimble exports Contacts, Companies, Deals, and Activities through a CSV export capped at 500 records per email-delivered file, which requires batched extraction and reassembly before any mapping to Twenty's People, Organizations, and Opportunities schema. We sequence parent objects first (Organizations before People) to satisfy Twenty's foreign-key structure, remap Nimble tags to Twenty's tagging system, and handle Custom Data Fields through the CSV import wizard. Workflow automations, email sequences, and social enrichment URLs do not migrate as code or data. We deliver a written workflow inventory so your team can rebuild automations manually in Twenty.
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 Nimble 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.
Nimble CRM
Contact
Twenty CRM
Person
1:1Nimble Contacts map to Twenty Persons. The Contact's name, email, phone, address, social profiles (LinkedIn, Twitter, Facebook URLs), and any Custom Data Fields transfer via CSV export and bulk import. Nimble's social enrichment URLs are stored as text fields on the Person record in Twenty; they do not receive live enrichment. We resolve the parent Organization by exact name matching from the Nimble Company field to preserve the Person-to-Organization relationship.
Nimble CRM
Company
Twenty CRM
Organization
1:1Nimble Companies map to Twenty Organizations. The company name, domain, industry, address, phone, and any Custom Data Fields transfer. We export Organizations first in the migration sequence to ensure that the Organization exists before any Person import that references it. Name-based lookup resolution is the primary dedupe mechanism; domain is stored as the website field and used as a secondary dedupe signal.
Nimble CRM
Deal
Twenty CRM
Opportunity
1:1Nimble Deals map to Twenty Opportunities. Deal name, value, stage, owner, expected close date, and loss reason fields transfer. Nimble's pipeline stages map to Twenty's Opportunity stage labels, which we configure before migration. Closed-Won and Closed-Lost reasons from Nimble custom fields map to Twenty's lossReason field if present, or to a custom text field for manual categorization in Twenty.
Nimble CRM
Pipeline Stage
Twenty CRM
Opportunity Stage
lossyEach Nimble deal pipeline and its associated stage values are documented during scoping and configured in Twenty as Opportunity stages with custom labels. Stage probability weights are set per stage in Twenty's pipeline configuration. The customer chooses whether to replicate Nimble's stage set exactly or consolidate during migration for a cleaner Twenty pipeline.
Nimble CRM
Activity: Task
Twenty CRM
Task
1:1Nimble Task records export via CSV with a hard ceiling of 500 records per export file. Large task histories require multiple export requests and reassembly before import into Twenty. We flag any Tasks beyond the export ceiling as a written inventory item for manual follow-up. Task subject, status, due date, and assignment transfer; body text migrates as the Task description field.
Nimble CRM
Activity: Logged Call
Twenty CRM
Task (Call subtype)
1:1Nimble Logged Calls map to Twenty Tasks with the call subject and duration preserved. Call disposition and notes transfer to the Task description. We extract the call timestamp and set it as the Task due date or a custom activity timestamp field in Twenty. Call recording URLs are not natively transferable and are flagged as a manual-rebuild item if the customer uses call recording.
Nimble CRM
Activity: Event
Twenty CRM
Task (Event-like)
1:1Nimble Events map to Twenty Tasks with the event title, start and end timestamps, and location preserved. Attendee information transfers as a comma-separated list in a custom text field in Twenty since Twenty does not have a native EventAttendee model in the same way as Salesforce. Meeting notes migrate as the Task description.
Nimble CRM
Custom Data Fields (Contacts)
Twenty CRM
Custom Fields (Person)
lossyNimble Custom Data Fields on Contacts map to custom fields on the Person object in Twenty. Field types (text, picklist, date, boolean, number) are mapped to equivalent Twenty field types during the schema setup phase. Picklist values are recreated as options in Twenty's field configuration. We export custom field definitions from Nimble during scoping and pre-create the corresponding fields in Twenty before any Person import.
Nimble CRM
Tags
Twenty CRM
Tags
lossyNimble tags (flat label associations on Contacts and Companies) transfer as tags on the equivalent Twenty record. Multi-value tag fields may need splitting if Twenty's tagging model requires single-tag-per-association on bulk import. We export all tags per record as a comma-separated string in a custom field for initial import, then create native tag assignments from that field. Tag strategy is confirmed with the customer during scoping.
Nimble CRM
Owner
Twenty CRM
User
1:1Nimble Owners (users assigned to Contacts, Companies, and Deals) map to Twenty Users. We resolve owners by email match during import. Any Nimble Owner without a matching Twenty User is held in a reconciliation queue for the customer's admin to provision the Twenty User before record import resumes. Owner assignment on Opportunities transfers by email lookup.
Nimble CRM
Messages / Communications
Twenty CRM
Note (or external reference)
1:1Nimble message records store outreach history including recipient, timestamp, and type (email/sequence). Full email body content may not transfer cleanly due to HTML formatting differences and storage constraints. We capture recipient, timestamp, and type as a Note on the Person record in Twenty. Full message body migration is scoped as a separate effort if the customer requires it.
Nimble CRM
Attachments
Twenty CRM
Attachments
1:1Attachments stored within Nimble's 2GB per-user storage limit are extracted as metadata and re-linked where possible. Full binary attachment migration is not included by default due to the storage constraint on the source side. We document attachment count and total size during scoping and flag any attachments at risk of being lost due to the storage ceiling.

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.
Nimble CRM gotchas
API lacks Task CRUD and bulk operations
2GB per-user storage ceiling is tied to email history
Workflow automations have no export path
CSV exports capped at 500 records per email delivery
Email sequences and outreach templates not exportable
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
Discovery and export planning
We audit the Nimble CRM account across record counts (Contacts, Companies, Deals, Activities), Custom Data Field definitions, active Workflow count and complexity, tag taxonomy, attachment volume, and storage consumption against the 2GB per-user ceiling. We plan the CSV export batches based on record counts, calculating the number of 500-record export rounds required for each object. The discovery output is a written migration scope, an export schedule, and a schema map identifying which Nimble fields map to which Twenty fields including any required custom field creation in Twenty before data loads begin.
Schema setup in Twenty
We set up the Twenty destination schema before any data import. This includes creating any custom fields on Person and Organization objects to receive Nimble Custom Data Fields, configuring Opportunity pipeline stages to match Nimble's deal stages, and provisioning Twenty Users to match the Nimble Owner roster by email. The self-hosted Twenty instance must be running and accessible via its API or database connection for us to execute the schema setup and data loads.
Batched CSV extraction from Nimble
We initiate Nimble CSV exports for Contacts, Companies, Deals, Activities, and Tags in batches of 500 records. Each batch arrives via email and is downloaded, deduplicated, and reassembled into complete datasets. For large databases, we stagger export requests to avoid Nimble's email delivery throttling. Tasks are the highest-risk object due to the API lacking CRUD, so we prioritize the Task export early to confirm the data volume before committing to the full migration schedule.
Data transformation and field mapping
We transform the exported CSV data to match Twenty's field names and types. Name-based lookup resolution pairs Nimble Contact.company (a free-text company name) to the Nimble Company.name being imported as a Twenty Organization, ensuring the Person-Organization relationship is established before Person import. Tags are normalized to Twenty's tagging format. Custom Data Fields are type-checked against Twenty's field definitions. Any data quality issues (duplicate emails, missing required fields, malformed dates) are flagged in a pre-load reconciliation report for the customer's review before we write to Twenty.
Production import in dependency order
We run the Twenty import in dependency order: Organizations first (from Nimble Companies), then Persons (from Nimble Contacts with OrganizationId resolved), then Opportunities (from Nimble Deals with PersonId and OrganizationId resolved), then Tasks and Notes. Owner assignment resolves by email lookup to Twenty Users at import time. Each phase emits a row-count reconciliation report before the next phase begins. If the Nimble storage ceiling was approached before export, any attachments or email history at risk are flagged in the reconciliation report.
Cutover, validation, and workflow rebuild handoff
We freeze Nimble writes during cutover, run a final delta migration of any records modified during the migration window, then mark Twenty as the system of record. We deliver the Workflow and Sequence inventory document, the Custom Field mapping spreadsheet, and the tag taxonomy mapping to the customer's admin team. We support a one-week hypercare window for reconciliation issues. We do not rebuild Nimble Workflows as Twenty workflows inside the migration scope; that is a separate configuration engagement or an internal admin rebuild task.
