Can I migrate to a new server instead of upgrading. Unsolved issues with webfinger, nodeinfo and Collabora when upgrading to 21.0.7

I definitely had these problems as I described. I tried a lot to solve them in vain.
For the webfinger you can see these threads which shows that I was not the only one having the problem.

For the Collabora there are also a lot of threads from others having problems. In my next try I will purge docker before upgrading and then reinstall docker from scratch. I hope it should solve that problem :wink:

My current php is 7.3 which is no longer supported and 7.4 is getting close to EOL. php8.0 seems to be the recommended version, but I can wait with php and Ubuntu.

But I first need to upgrade from NC20.0.14. I guess I will go further to NC22 once I have managed to get to NC21.
