Upgrade from 4.0.8 to 7.2.3 causes missing spaces

[xImMoRtALitY99]

Describe the bug

After upgrading from version 4.0.8 to 7.2.3 the users space doesn't load anymore nor can I create new ones.

Steps to reproduce

1. Have a running instance with version 4.0.8
2. Upgrade to version 7.2.3 as it is mentioned on https://docs.opencloud.eu/docs/admin/maintenance/upgrade/upgrade-7.x.x
3. Start the instance and wait for the migration to finish, all spaces are gone from the WebUI.

Expected behavior

All spaces and data being shown after the upgrade.

Actual behavior

The space of the logged in user doesn't show up and new spaces can't be created.

Setup

Please describe how you started the server and provide a list of relevant environment variables or configuration files.

Additional context

I already found out that it seems related to the following environment variables:

OC_CACHE_STORE_NODES=valkey-sentinel:26379/myprimary
OC_CACHE_STORE=redis-sentinel
OC_CACHE_TTL=6h

The issue with the upgrade doesn't occur if the default cache store "nats-js-kv" is used.
