## A scope you can sign off

Our engineers use the map to plan the migration. We agree the deliverables, checks and fixed price with you before work starts.

## Check before you switch

We rebuild the reports people actually use and check them against the originals. We run trial migrations and reconcile the data before cutover.

## Keep what you have built

Your definitions, maps and reports stay on Rig. You can reuse them in later projects.

Customer story / A UK IT services group

## How four merged IT services companies narrowed 58 systems to the seven that matter

After the merger, the group needed to move onto one Dynamics 365 platform. Mapping all 58 of their systems and recording how the work actually runs narrowed the job to seven core systems, with a working replica to test before anything cuts over.
