EV9.0.2 to EV10 upgrade/migration, roll back possible?

This issue has been solved. See solution.

Hello All,

I will start by saying I am not real familiar with the Enterprise Vault software.  I have a client currently on EV 9.0.2 and wants to upgrade to EV10, but only if it is possible to go back to EV9 if anything seems off.  

I have read through the documentation and forum discussions on the upgrade and have begun to prepare the new 64-bit VM for this upgrade.  The question is this, after running the migration wizard to move the data from the EV9 environment into the EV10 environment, is it possible to revert back to EV9 and if so, what are the steps involved?  Correct me if I'm wrong, but it sounds like pointers inside the exchange mailboxes are changed during this migration.  So if I were to be required to revert, would I have to restore the exchange environment to a state prior to the migration as well as restoring SQL and EV9?  

Thanks in advance for any light you can shed on this for me.

You won't have to do anything with Exchange, you would need to restore the EV SQL databases.

Honestly, if you aren't familar with EV should you really be doing this?  You might consider sub-contracting out to a partner that does have EV expertise.

During the upgrade, nothing happens in Exchange.
It's only EV, partition data, and SQL. (And partition data isn't touched unless you're moving it from one machine to another).

Sounds like you need a partner to help you through though. For safety.
