Question about Exchange 2010 SP1 RU2 update

Not open for further replies.

Microsoft released a new RU2 update package for Exchange 2010 SP1.

On the bottom of the page, under " Prerequisites" , it says:

The following list contains prerequisites for the Update Rollup 2 for Exchange Server 2010 SP1:
Install Exchange Server 2010 SP1 on the computer before you apply this update rollup. Remove all interim updates for Exchange Server 2010 SP1 before you apply this update rollup.

So, my question is: do I have to remove RU1 if I have it installed? Normally, as far as I know, you never have to remove any old updates, but simply install any new ones. That prereq threw me off there... Is it required to remove RU1 before applying RU2?

No, you do not. That is referring to any update that wasnt publically available that you installed. ( something from PSS )

Brian Day MCITP

Andy is correct (like usual). :)

Service Packs and Update Rollups are cumulative.

So a SP2 (even though one doesn't exist) would contain all SP1 fixes.

RU2 contains all RU1 fixes, etc...
