CRM migration to a self-hosted Twenty CRM you own

Who this is for

Teams that have outgrown their rented CRM. The subscription climbs every year, the data model never quite fits how the business sells, and the most important asset the company has, its prospect and customer history, lives inside a vendor's walls, shaped by the vendor's defaults. If you have started to think of the CRM as something you work around rather than with, and you want a system the business owns the way it owns its other equipment, this is the engagement for that.

It is not for everyone. Self-hosting trades a subscription for operational responsibility, and the audit phase exists partly to tell you whether that trade is worth making. We have told clients to stay where they are. Our honest take on the decision is in Should You Self-Host Your CRM?

What we deliver

A self-hosted Twenty CRM instance running on infrastructure you control: your virtual machine, your database, your backups. Twenty is open source, so there is no licence fee and no vendor who can change the terms underneath you.

The data model is designed around your real sales motion, not the defaults a rented CRM ships with. If you qualify prospects by category and territory, those become first-class fields with controlled values. If you sell against a calendar, the calendar becomes an object. The schema design session with the people who actually work the pipeline is consistently where the most value in the engagement surfaces.

The migration itself runs under written sanitization rules that you approve before a single record moves: what makes a record valid, which duplicates merge, which field wins when two records disagree. Validation is statistical, not anecdotal: we draw seeded random samples so the spot-checks are reproducible and anyone can re-run them. Every change ships with a staged rollback script, written and tested before the change runs. Cutover happens in a planned window with the old system frozen, a smoke test before anyone is told the new system is live, and the legacy CRM held read-only afterward as a reference.

The engagement ends with an admin runbook, live training on your data, and a formal handover: credentials rotated into your hands, our standing access removed unless you choose a support arrangement. A self-hosted CRM you cannot operate is not owned; it is rented from the consultant instead of the vendor.

The four-phase protocol

Audit. A utilization report on the current CRM: which features are used, which are paid for and ignored, where data quality has decayed, and every integration and automation hanging off the system. It produces the migration decision, the baseline acceptance criteria, and the timeline. Gate: you review the report and decide whether to proceed.

Implementation. The new system is built before any legacy data touches it: Twenty deployed on your infrastructure, schema designed around your sales motion. Gate: you work the new system against the agreed design and sign off.

Migration. Data moves under the written rules, validated by seeded spot-checks, with rollbacks staged for every change and a planned cutover window. Gate: the validated dataset is compared against the audit baseline and you approve cutover.

Training. Runbook, live training, formal ownership transfer. Gate: handover is confirmed complete, with access verified in your hands.

The gating is the point. Each phase produces something you can review and approve, so a problem is caught at that phase instead of compounding into the next one.

Proof

We ran this protocol first on Sprout IQ, our own publishing business in Belleville, Ontario, before offering it to anyone else: 8,000+ company records migrated under strict validation, 117 n8n workflows in production (as of June 2026) deployed from version control, and a website replatform that held search rankings across 795 URLs. The full playbook, including the failure modes of skipping each phase, is documented in Migrating from Pipedrive to a Self-Hosted Twenty CRM.
