How do you prepare your business for an ERP go-live?

In the 4 weeks before go-live: complete final user acceptance testing, finish all staff training, run parallel testing with real transactions, ensure your opening data is clean and imported, confirm all integrations are working, prepare a cutover plan with a clear go/no-go decision point, and arrange for hypercare support (daily vendor or partner check-ins) for the first 2-4 weeks post-launch.
