Short answer: No — don't cancel anything the day you switch. Run the old and new setups side by side for a few days, verify your records (chip and registration numbers first, then links and listing statuses), and only cancel Wix and archive the spreadsheets once everything checks out. Keep a dated spreadsheet snapshot indefinitely as a backup, even after you cancel.
Why parallel-run
A migration looks done before it's done. The records are imported, the pages render, the listings show up — and then a chip number turns out to be rounded, or a redirect isn't firing, or three reservations didn't carry their statuses. If Wix and the spreadsheets are already gone, you're rebuilding from memory. Keep them live a few days and the old system is your reference for checking the new one.
What to verify, in order
- Chip and registration numbers. First and most important — full length, leading zeros intact, no scientific notation. A corrupted ID is the error that hides. (See Why chip and registration numbers break in spreadsheets.)
- Links and references. Pedigrees connect to the right sires and dams. Puppies sit under the right litters. Health results attach to the right dogs.
- Listing statuses. Available, on hold, pending, reserved, sold — each puppy reads correctly on the public side.
- Redirects. Old Wix URLs land on the right new pages, not 404s. (See Will moving off Wix hurt your rankings?)
When it's safe to cancel
Once those four check out, cancel Wix and archive — don't delete — the spreadsheets. Archiving costs nothing and gives you a fallback. Deleting gives you nothing back if a question comes up in a month.
Keep one snapshot forever
Save a dated copy of your final spreadsheet export and set it aside for good. It's the cheapest insurance you'll ever buy: if you ever need to confirm what a record looked like before the move, it's right there. Date it clearly so future-you knows exactly what it is.
