Veeam Backup replication upgrade fallbackup plan

[Iliyasmomin77]

We are going to upgrade Veeam backup & replication V9.5 4.2866 to V11.
If upgradation went fail , what will be the fall backup plan of upgrade. Will be taking configuration backup before upgrade

Hi Iliyas, to get back to the configuration you had before the upgrade, you would need to just install a clean instance of v9.5 with the corresponding patches/updates and import configuration backup there.

So if we fail on upgrade to Veaam backup & replication V9.5 4b or V11, or V11 is not working for our backups . We have uninstall V11 & Again clean install V9.5 4b is it?
