Frequently asked questions

How do you ensure no data is lost?

We reconcile record counts and key values before and after migration, and run trial migrations so issues are found and fixed before go-live.

Can you migrate from a very old system?

Yes. We regularly extract data from legacy and even unsupported systems using a range of techniques.
