Migration from plain Docker to Grocy Home Assistant Add On

[hklages]

What is the best way to migrate from an external grocy Docker instance (in my case hosted on Synology NAS) to Home Assistant Add On?

What I did:
I installed Home Assistant Add On Portainer, selected the running Home Assistant Grocy instance, started the console and copied the file "grocy.db" and "custom_js.html" from my existing Synology Docker installation to the \tmp with "wget".

Then I copied both data to the \data\grocy directory overwriting the existing files. Finally did a restart of the Grocy Add on. Tried to do the "copy and restart" quick to reduce the risk of db inconstencies.

So far it works - all my about 30 chores, 100 equipment items are available in Home Assistant. Journal is also ok.

Any other solution? I am not so happy with this approach because overwriting a db is - in general - not a good procedure and might cause inconsistencies.
