CRM migration moves contacts, deals, activity history and attachments from a legacy CRM or spreadsheets to a new platform without data loss. Codazz profiles, cleanses and de-duplicates records, runs a full dry run with reconciliation reports, and keeps a rollback snapshot through go-live — fixed-price scope, 200+ developers.

What We Move

CRM Migration Services

Data Profiling & Audit

Before anything moves we profile every table — completeness, duplicates, orphaned records, dead fields and the three different date formats someone has been typing since 2017.

Cleansing & De-Duplication

Fuzzy matching, merge rules and survivorship logic agreed with your team, so you land in the new CRM with a clean database rather than importing a decade of mess.

Field Mapping

Every source field mapped to a target field or explicitly retired, documented in a mapping sheet your team signs off before the first load runs.

History Preservation

Activity history, emails, call logs, notes, attachments and closed deals migrated with their original timestamps and owners — not flattened into a single import date.

Dry Run & Reconciliation

A full rehearsal into staging with reconciliation reports on record counts, pipeline value and open items, verified by your team before production is touched.

Cutover & Rollback

A rehearsed cutover window with a frozen source snapshot and a rollback path that stays available through the first weeks of go-live.

Our Process

Our CRM Migration Process

  1. 01

    Audit & Scope

    Source system profiling, data quality report, volume analysis and a written scope covering exactly which objects, history and attachments move and which are archived instead.

  2. 02

    Cleanse & Map

    De-duplication and cleansing rules applied to a working copy, field mapping documented and signed off, and target-side validation rules configured to keep the new system clean.

  3. 03

    Dry Run

    A complete migration into staging with reconciliation reports. Your team works in the staged data for a week and raises anything that looks wrong while it is still cheap to fix.

  4. 04

    Cutover & Verify

    A rehearsed production cutover in a defined window, post-migration verification against the reconciliation baseline, and rollback kept live until sign-off.

CRM Migration FAQ

CRM migration cost, history preservation, dry runs, rollback plans and downtime during cutover.

Ask our team
  • Migration cost is driven by data volume, how many source systems are in play, how heavily customised the legacy CRM is, how much activity history and how many attachments have to come across, and whether it is a multi-entity consolidation. Every quote is fixed-price after a free data audit, so volume surprises are found before you commit, not after.
