Through this video, I'll show you how to upgrade VCS Server, this procedure works for VCS-C, VCS-E, EXP-C and EXP-E.
Since I'm in the 8.x major release, this does not require a new release key.
This video is no replacement for reading the documentation on the upgrade, and also the Release Notes for the product. This is only meant to be a visual guide of how the procedure will look like, so you can have a reference for the time when you do this.
All the related documentation, can be found here:
