So much changed from 5 to 7 that a re-install is almost certainly the
way to go. How exactly you port your config depends entirely on what
programs you are talking about.

The best idea is to create a virtual machine (or install centos 7 on
spare hardware), figure out how to configure the applications and the
process to restore the data from backups. Once you know what to do (and
have documented it), reinstall.
