What guided review can help with
Guided review can help identify likely field meanings, risky assumptions, and places where your current export structure may need clarification.
It can also help separate obvious mappings from judgment-heavy relationships that need church-side confirmation.
What should not be implied
A field with a familiar name should not be treated as proven just because it looks similar to a Transparent concept.
Migration help should never imply that every relationship, household rule, or custom field can be mapped automatically without review.
