Start with the catalogue
Test codes, reference ranges, specimen types and pricing are migrated and reviewed by the lab team before anything else. A clean catalogue prevents most errors seen after go-live.
Run in parallel where risk is high
For critical sections we run old and new side by side for an agreed period, comparing results and turnaround until the team signs off.
Cut over section by section
Instead of one big switch, sections move one at a time, each with a reconciliation report and a named contact on site. The bench keeps working throughout.
