Dedupe Contacts

A DiveShop360 import creates placeholder records (an email like ds360+name@import.…) for students who often already existed. "Merge Import Duplicates" finds each placeholder with a real twin and folds it into the real record. Admin and manager only.

Scan, then merge

1. Press "Scan for duplicates". This changes nothing; it lists every placeholder that has a real twin.
2. Review the "Delete (placeholder) → Keep (real record)" pairs. Open "skipped (no clear match)" to see the ones held for manual review and why.
3. Press "Merge all N →" and confirm "Merge and delete". Use "Re-scan" afterwards to confirm the list is empty.

What a merge does

• Every linked record — certifications, training records, orders, documents, waivers, roster entries, texts, class-day notes and a child’s guardian link — moves to the kept record.
• Blank contact fields on the kept record (phone, date of birth, secondary email, address, notes) are filled from the placeholder.
• The placeholder is then deleted, all in one transaction, so a failure part-way leaves nothing half-moved.

What it never merges

• The kept record’s email and any field it already has. Only blanks are filled; nothing on the real record is overwritten.
• A name-only match. Two different people can share a name, so the live merge also needs a phone, date of birth or secondary email to agree. Those pairs are listed for review instead.
