Our CSP end (recovery site) is running ZCM and ZVM both at version 7.5. Our customers protected end is a mix of 7.0 and 7.5. Now I know we have to upgrade the customers from 7.0 to 7.5 at least first to get any higher … but can our customers go on to version 8.0 (so one version behind the CSP end which will be left on 7.5)? … or does the ZCM/CSP end need to be same or one higher version than the customer end?
As long as you are within 1 major version EG 7.5 –> 8.0 is ok
Please remember to read the release notes for interoperability for newly paired sites as this may vary due to technical changes in the software.
If you need further help your account team will be able to provide more details on your specific setup.
