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.
Move off legacy CRM or spreadsheets without losing records — profiling, cleansing, dry runs and rehearsed cutover with rollback.

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.
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.
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.
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.
Activity history, emails, call logs, notes, attachments and closed deals migrated with their original timestamps and owners — not flattened into a single import date.
A full rehearsal into staging with reconciliation reports on record counts, pipeline value and open items, verified by your team before production is touched.
A rehearsed cutover window with a frozen source snapshot and a rollback path that stays available through the first weeks of go-live.

Open toolCRM migration cost, history preservation, dry runs, rollback plans and downtime during cutover.
Ask our teamMigration 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.
No. Emails, call logs, notes, tasks, attachments and closed deals migrate with their original timestamps and record owners, not flattened into a single import date. Where a target platform has a hard limit on a particular object type we tell you during the audit and agree an archive strategy in advance rather than discovering it at cutover.
A full dry run into staging, followed by reconciliation reports covering record counts by object, total open pipeline value, open activity counts and attachment totals against the source. Your team then works in the staged data for a week. Production cutover only happens after that sign-off.
The source system is frozen and snapshotted before cutover, and the rollback path stays available through the first weeks of go-live. Because the dry run already validated the exact same scripts against the exact same data, cutover-day surprises are rare — but the rollback exists precisely so nobody has to gamble.
Yes, and it is one of the most common starting points. Spreadsheet migrations need more cleansing work up front because field discipline is usually inconsistent, but the process is the same: profile, cleanse, map, dry run, reconcile, cut over.
Usually a single weekend, and often no downtime at all. The source system stays live and in use until the cutover window; the new system is loaded and verified in staging beforehand. Only the final delta load happens during the freeze, which is measured in hours rather than days.
We profile your existing records, show you the duplicate and data-quality picture, and quote the migration fixed-price.
