@everyone
We have a live version of appwrite that was running on 1.2.1, we want to migrate to appwrite cloud but, in order to do that we have to migrate to 1.4.x.
To do this, we're upgrading from 1.2.1 to 1.3.0
While doing this in step 2 of the migration as per https://appwrite.io/docs/advanced/self-hosting/update
We're getting the following error
Migrating Collection cache:
Fatal error: Uncaught Exception: Collection not found in /usr/src/code/vendor/utopia-php/database/src/Database/Database.php:3827

docker ps output seems fine, all containers are up
Summary
Troubleshooting migration issues from version 1.2.1 to 1.3.0 in a self-hosted environment. Attempted unsuccessfully to run migrations. Received a fatal error related to a missing collection. Proposed solution: try clearing cache tables and running migrations sequentially for each version (1.2.1, 1.3.0, etc.) while ensuring backups are in place.
