Will Exchange 2010 SP3 Upgrade Break EV Components in OWA?

Hello Everyone,

We're planning to upgrade our Exchange 2010 environment from SP2 to SP3. And since there is EV component in OWA 2010, I am worried that this might break once Exchange 2010 SP3 is installed. If anyone has any experience with the same, I hope you can help answer my questions:

1. Will upgrading Exchange 2010 SP2 to SP3 break the EV component in OWA 2010? (Archive Explorer, Search Archive)

2. If it does break, what are the options of reinstating this functionanility/feature?

We have no test environment for us to have this tested properly.

Thanks!
