Upgrading DCS 6.6MP1 to 6.7MP1 - screenshots/videos available?

Running currently DCS 6.6MP1 with seperate UMC virtual appliance. Has anyone upgraded to 6.7MP1 from 6.6Mp1? Any issues, workarounds etc...

Also what complete files would be required for rollback and backup of 6.6Mp1?

I have the upgrade steps from the 6.7MP1 documentation, but looking for a graphical installation guide/video for upgrading from DCS 6.6Mp1 to 6.7?

I do have all documentation for 6.7MP1 and the installation guide/video for 6.7MP1.

Any assistance will be useful as we need to upgrade to 6.7Mp1 asap.
