What to gather before review
Bring a sample export, the name of your current system, and a short list of the records that matter most to your team first.
If multiple stakeholders need to sign off on migration confidence, name them early instead of treating migration as a solo admin question.
What readiness does and does not mean
Readiness means your church can describe its data, questions, and likely cleanup needs clearly enough for guided review to be useful.
Readiness does not mean every field, relationship, or exception is already proven safe for one-pass import.
