We need to migrate lots of images from our old site in EPiServer CMS 7.1 to our new site in EPiServer CMS 7.5. When connecting to our old site using the VPP migration tool I encounter an error:

Object reference not set to an instance of an object.

I made sure our old site is running before the VPP migration.

Sorry I forgot to migrate the old site first to 7.5 via Deployment Center. Now I encounter a different error message:

Make sure you have the latest version of the EPiServer UI from the add-on store.
Optionally, install a fresh alloy site, and copy the files from appdata\modules and appdata\modulesrepository, along with wwwroot\modulesbin
