Concerns when migrating from PHP 5.6 to 8.4 [closed]

I am currently using PEAR and considering migrating from PHP 5.6 to PHP 8.4 for our current site.
Does the latest stable version of PEAR (1.10.16) support PHP8.4?
Or should I discontinue PEAR and move to Composer?

I’d like to avoid major renovations as much as possible.

Package in use
HTTP_Request2, OS_Guess, Net_URL2
