There are changes in httpd 2.4 debian 8 vs httpd 2.2 in debian 7 that 
are "above" just getting a mod_perl that works with apache 2.4 where 
your application might need some code changes to support both.

For example, paraphrasing a post I wrote a few days ago, if you look at 
https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7197 and 
https://svn.apache.org/viewvc?view=revision&revision=1681228, you'll see 
how the changes in httpd 2.4 rippled down to MP and how I implemented 
$c->client_ip instead of $c->remote_ip.

The documentation at 
http://httpd.apache.org/docs/2.4/developer/new_api_2_4.html about the 
changes is a good starting point.  Beyond that, I would look at error 
logs to see if you have any specific issues to comment on.
