We are upgrading from 22.214.171.124 to 7.7.3. Is there any technote which says that the older images backed up with 126.96.36.199 can be restored form 7.7.3 with out any issue.
I know this can be done, but needs a technote or document to suport this information.
Or is there any way we get from Veritas.
I have not seen such a TN.
This kind of support is a built-in ability of any kind of backup software without the vendor needing to state it explisitly.
What good would 'Infinity' retentions be without future versions being able to read the backups?
If you need confirmation in writing from Veritas, you will need to log a Support call.
Restore exceptions are listed here: https://sort.veritas.com/nbufutureplans
Yes it will be restored to the latest one, there is no specific Tech note on this i did from 188.8.131.52 to 7.7.2 on around 4 master and 8 media servers. i did'nt see any issues.
