Exchange 2007 SP1 to SP upgrade (prep for Exchange 2010)

Hi

Environment:
2x HUB/CAS SP1 (running on Windows 2003 SP2 x64)
2x Cluster Nodes running SCC Exchange 2007 SP1 (windows 2003 SP2 x64)
1xAD domain (multi-site) - Windows 2003 x86 SP2 Native

When running the SP2 install from one of the Exchange servers and during the 'Organization Preparation) it initially says checks are ok then it goes onto o fail with the following;

Error:
The well-known object entry with GUID 73000302-5915-4dce-a330-91dd24f58231 on the otherWellKnownObjects attribute on the container object CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=sub,DC=domain,DC=org refers to a non-USG CN=Exchange Public Folder Administrators,OU=Microsoft Exchange Security Groups,DC=sub,DC=domain,DC=org. Please either delete the well-known object entry or promote the target object to a universal security group.

Now I have checked this group and it is indeed a USG.

The reason I am a little more concerned, is that I had built a lab which was a direct replica of the prod AD and I also ran recovery to rebuild the exchange infra in the lab so it is an exact config replica also.

Now the SP2 here went fine and the new Exchange 2010 attributes were added to the schema.
I have search for an answer and so far can only seem to find a solution stating to clear the attribute in ldp but I am a little reluctant to jump straight in with trying that on my prod setup.

Both the prod and lab LDP attribs are showing exactly the same values.

As I say, in the lab it went fine with no issues at all...

Any ideas?

Regards
Bryan

hi steinmto

thanks for getting back. i did stumble across this previously and had my lab not been a replica setup (with the same attrib values afaik) then i would go ahead with it.

I just need to be really cautious as I do not want the prod exchange to go bang and give me major problems :-)

hi jjdurrant

thanks - ok, so just add a new blank value to otherWellKnownObjects atrrib should be fine?
Did you have to run any setup/prepareAD post this change or were all your Exchange groups still in place?

Thanks again.
Cheers

hi

apologies for delay - yes all worked out fine in the end. to note, I did have to run setup/preparead again and then re-populate some of the default exchange groups (to enable my clusters to work etc) but no major issues.

Thanks for the replies and I hope the points split is ok..
