Consolidating a Fragmented CRM and Business Systems Estate into the Cloud

Assessment started with a data quality audit before any architecture: duplicate rate, field completeness, and definitional conflicts were measured across all source systems. Migrating dirty data into a clean platform reproduces the original problem at higher cost, so remediation scope was agreed at this point, not discovered later. Process mapping ran against actual behaviour — what the team does, versus what the documented process says — because the gap defines configuration scope. An integration contract inventory captured, for each connected system, what it reads, writes, and assumes. And the cost model covered licensing, implementation, integration rebuild, data remediation effort, and ongoing operations, compared against the fully-loaded cost of the status quo — including manual reconciliation labour.

Sequencing was phased by business function, with each phase delivering usable value rather than partial infrastructure: data consolidation and deduplication into a single customer master; the core CRM stood up in the cloud with the sales function live first — it had the clearest process and the most motivated users; the service function migrated with its case history; integrations rebuilt against the new platform; and legacy decommission only after a full period of parallel operation.

Validation ran per batch and per function: record-count and field-level reconciliation on every migration batch; business process walkthroughs with users from each function executing their real daily tasks in the new system before their phase went live; integration verification with every connected system confirming reads and writes under production-like volume; and parallel operation with the legacy system readable but frozen, so any missing record could be checked rather than assumed lost.

Ongoing operations covered configuration changes as processes evolve, integration monitoring, user enablement for new hires, and periodic optimization. The decommission of the legacy estate was treated as a deliverable with its own checklist, not as something that happens on its own — orphaned legacy systems are the most common unbudgeted cost after a CRM migration.
