Import of 2020.12.1 snapshot into 2021.2.1 caused invalid config and recorder issues

Configuration
1

Given that I found my 2020.12.1 Home Assistant installation classified as “unhealthy” due to e.g. an unsupported host OS, network config, I wanted to migrate to a supported vm appliance setup with the provided virtual hard drive. I therefore exported a snapshot of the old version and imported only the configuration as well as the local add-ons into the new 2021.2.1 setup.
Now I see the following errors in the notifications:

Invalid Config
The following integrations and platforms could not be set up:

  • recorder
  • history
  • logbook
  • default_config

Please check your config and logs.

as well as

Recorder
The recorder could not start, please check the log

However, the logs show no new messages, and when I load the full logs only:

2021-02-09 07:40:11 WARNING (MainThread) [homeassistant.loader] You are using a custom integration for hacs which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant.

All my history graphs in lovelace show “History integration disabled”.

Does anyone have a clue where I should start debugging / fixing this?

Try deleting your recorder database and restarting.

config/home-assistant_v2.db if using the default database.

Thanks a lot!
Note for others encountering similar issues: I needed to restart the host, restarting the supervisor wasn’t sufficient it seems.

Sorry, I should have been clearer, restart Home Assistant.

Same issue after restoring the old snapshot, deleting the .db and restarting help. Thanks.
