Downgrading Veeam ONE from v13 to v12.

Hi ​@Madi.Cristil ​@safiya ..when you get a chance, can you place this post in the ‘Discussions Board’ please, for higher visibility?

Thank you.

​@waqasali -

I’m pretty sure there is no ‘downgrade path’. I believe the only thing you can do is uninstall current and reinstall previous version.

thank you ​@coolsport00 , for highlighting!

This is a good idea. I will wait for other participants' suggestions. 

A downgrade of Veeam ONE is not possible and if you go for the reinstall option, you would have to start with a new database and configuration. 

Hope you have snapshot of VM ....

yes i have too

yes right but in that case data is supposed to be lost on db side please correct if i am wrong.

Pretty confident that a downgrade isn’t possible since the database structures and contents will have changed during the upgrade so you’ll have to revert your snapshot or re-install ONE v12.

There is no supported way to downgrade from a higher version to a previous version without doing a full uninstall of the current version and reinstalling with the desired version. Restoring the configuration will require a configuration backup from that particular version.

Neither configuration backups nor backups made with a newer version of Veeam can be used with previous versions (Veeam is backwards compatible with backups, meaning v13 can work with v12 backups, but v12 cannot work with v13 backups)

What is the reason for wanting to downgrade? If there are technical issues on v13, it’s best to open a Veeam Support case and let Support review the behavior.
