Moved from VSE to EEPC group.
Specifically what? Without knowing your hardware etc its impossible to say.
Best thing to do is check the upgrade paths and processes in the Installation guide and the readme file that comes with the version of EEPC. then check the known issues for that version.
Use EEGO to check your clients before deployment and also possibly the pre-boot smart check feature.
Also, you may want to upgrade to the latest version.
