Is migration possible for BE 2014

Hey all,

I was wondering if there is anything that can be migrated from one server with Backup Exec 2010 R3 SP4 to another server with Backup Exec 2014?

I have searched other posts and it sounds like migration is only possible when installing over the top of an already installed BE

Will catalogs be compatible when copied over? (I assume the Data folder can't just be copied as that would mess it all up)

A clean install may still be good anyway just to make sure there is no clutter. (If migration is not possible)

Thanks!
Steve
