Prepare AD for Exchange 2010 sp1 to sp2 upgrade.

Hello, I'm preparing to upgrade my Exchange 2010 site from SP1 (RU6) to SP2 (RU5)

I can find documentation for running the following AD prep steps

setup /PrepareSchema (/ps)

setup /PrepareAD (/p)

but I don't see any reference in either the release notes or installation examples of needing to run the last step usually required for Exchange AD preparation.

setup /PrepareDomain (/pd) or (/pad)

Since to domain objectVersion attribute stays at 13040 from SP1 to SP2 does that mean this last AD preparation step is not required in an upgrade from SP1 to SP2?
