I am planning on upgrading ZVMs to ver 7.5. Currently on 6.5 update 4 build 065404022. Are these versions inter-operable?
If you are talking about upgrading Zerto 6.5 to 7.5. It has to be done in two steps.
If you are talking about these to versions working in one setup:
Unfortunately, it’s impossible. Zerto versions need to be 1 version apart to work together and communicate.
So you would have to perform an upgrade of Zerto 6.5 to 7.0
