Is there a way to upgrade from Server 10.2.8 to 10.4 without upgrading MySQL and Perl. I have noted from many discussion boards that existing MySQL set ups get broken whether upgrading to 10.3 or 10.4. I have also run the upgrade on a test server and have had gotten major errors in relation to Perl, DBI, and DBD::MySQL. I would like to do the upgrade leaving my existing Perl, and MySQL as is, and upgrade that at my leisure.
