Failing to migrate AdoNet grain reminders from Orleans 3.7.2 to Orleans 7

[runenilsenoe]

Expected: Reminders running in 3.7.2 on AdoNet Reminder Persistence should work in new cluster after running the scripts on the bottom here: https://learn.microsoft.com/en-us/dotnet/orleans/migration-guide

Actual Reminders not running.

Repro: https://github.com/runenilsenoe/orleans7migrationtest

Steps to reproduce:

1. docker compose up
2. run 3.7.2 app which starts a reminder
3. stop and run migration script
4. run 7 app and wait for it to trigger reminder.
