Upgrade Debian from 10 to 11

[zawadaa]

Hi!
Recently I wanted to update Debian from 10 to 11.
But... changes in PHP packages (from now 7.4 is a default PHP i Debian) breaks all Wordpress vhosts.
Problem with FPM configuration etc.

Is there any solution for such operation?

I'm not recommending upgrade from deb10 to deb11 until we make walkthrough tutorial for that - because exim4 needs total fresh config file, and there are few things to execute in order to make upgraded deb11 working fine.
