Is it possible to rollback OneIM version from 9.0 to 8.2?

Context - We are planning to do version rollback as our OneIM version upgrade failed. Most of our sync projects are not getting migrated 

We have been getting Gateway timeout error on all the sync…

Hi Team,

As part of our upgrade activity, we are planning to migrate One Identity from version 8.2 to 9.1 very soon.

I was looking for any resource available which outlines the steps for performing the One Identity version upgrade activity.

Any documental…
