Moving from Ubuntu 22.04 to 20.04

I am having around 5 wordpress sites running on PHP 8.1 in cyberpanel that is installed in Ubuntu 22.04 server. Am shifting to another server with Ubuntu 20.04, and going to use cyberpanel there too. Will there be any issues, as I have read Ubuntu 20.04 only supports PHP 7.4 natively.

No its OK, Ubuntu 20 supports other PHP versions too.
