On the new server, there is a perl folder and a perl5 folder. My original webpage script was pointing to the perl folder

BEGIN {
    my $base_module_dir = (-d '/home/jeffer36/perl' ? '/home/jeffer36/
+perl' : ( getpwuid($>) )[7] . '/perl/');
    unshift @INC, map { $base_module_dir . $_ } @INC;
[download]

This produced an error because mysql.pm is located in perl5. So I added

It now finds mysql.pm but does not work.

At least on my webserver with cPanel installation of perl modules, the documentation for installing perl modules (not sure if it's cPanel or ISP documentation) lists a 'use' statement that will set up the use-lib properly for where cPanel installs the modules. Let me go look it up:

Your Perl script needs instructions to find the modules in your path.

To do this, add one of the two choices below to the top of your script:

#!/usr/bin/perl
use cPanelUserConfig;
[download]

- or -

#!/usr/bin/perlml
[download]

So, at least on my server, if I use the perlml version, it doesn't need the special include, but you might want to try the use cPanelUesrConfig; anyway (it may be that perlml is different on your cPanel than on mine).

Where do the files in /home/jeffer36/perl5/ come from?

What made them exist?

All files either in /home/jeffer36/perl5 or in /home/jeffer36/perl came pre-installed with the new server or were installed by using the module install feature in cPanel on the new server.
