You can check out the guide
http://world.episerver.com/documentation/Items/Installation-Instructions/Installing-EPiServer-updates/Upgrading-to-EPiServer-75-CMS/
Basically start with upgrading to 6 R2 then continue to 7 then 7.5.
Use deployment center and not nuget packages for upgrade. Best to keep a fresh demo site close to steal some settings from.
Looks like you have a problem with vpp. Tried to upgrade directly to 7.5? Used nuget instead of deployment center?
At 7.5 you also need to migrate vpp files to new media files. There is a tool that does that.
I'm trying to upgrade a CMS 6 installation to CMS 7.5 but whithout success. This is what I get:
