Binary file migration

This new release reduces the storage usage of binary files in half.

An online migration is included in version 5.5, allowing for minimal downtime as part of the upgrade. Before upgrading to Server Pro v6 make sure you're already running the latest version of Server Pro v5.5 (Release Notes 5.x.x) and have run the migration.

See full migration instructions.

MongoDB upgrade to v8

This release bumps the minimum mongo version to 8.0.

If you're currently using mongo v6 or earlier, you'd need to update your versions one major version at a time (v6 → v7 → v8).

Please ensure you have a database backup before upgrading. In case of roll-back, you will need to restore the database backup.

MongoDB v6 → v7 update

1. Update MONGO_VERSION in your config/overleaf.rc to MONGO_VERSION=7.0.

2. Start mongo v7 with bin/up mongo -d

3. Connect to the DB with bin/mongo

4. Ensure Feature Compatibility Version is set to 6.0:

> db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )
... 
featureCompatibilityVersion: { version: '5.0' }, 
...
> db.adminCommand( { setFeatureCompatibilityVersion: "6.0" } )
...
featureCompatibilityVersion: { version: '6.0' }, 
...

1. Start your Server Pro instance and verify you can login.

Mongo v7 → v8 update

1. Update MONGO_VERSION in your config/overleaf.rc to MONGO_VERSION=8.0.

2. Start your Server Pro instance and verify you can login.
