I always update my vbo365 server directly if it’s only a CU Update. I‘m not to worried about any issues after the patch. The vm is back-ed up daily with vbr in my designs. :)

Cumulative patches are normally not a great change.

Yeah we need to test it as we have developed a front-end portal for O365 so it could break that. :wink:

That’s true, the patches/CUs do rather small changes and until now didn’t create any problems.

Your welcome, @Nico Losschaert  :-)

I have updated some of my vbo servers. No issues with the backup jobs last night.
