Exchange 2010 SP2 Schema Upgrade

I have an existing Exchange 2010 SP1 installation.  
Here is how I applied the Schema update for Exchange SP2.

• Find out which DC is the Schema Master
• Stick Exchange SP2 somewhere on the network which is accessible by the DC
• Unpack the SP2 update

Run from the unpacked Exchange SP2 location...

• setup /PrepareSchema

It will throw up this prompt which is OK.

"Welcome to Microsoft Exchange Server 2010 Unattended Setup

Setup will continue momentarily, unless you press any key and cancel the

installation. By continuing the installation process, you agree to the license

terms of Microsoft Exchange Server 2010.

If you don't accept these license terms, please cancel the installation. To

review the license terms, please go to

Press any key to cancel setup................"

Wait for a success message:

"Extending Active Directory schema                         COMPLETED"

After that wait for an AD Replication to happen.

Then run the following.

• setup /PrepareAD

The same prompts will pop up and you should get the following success messages.

 "Organization Preparation                                  COMPLETED"

Again, wait for an AD replication to happen.

Now run the final command:

• setup /prepareDomain:<your.domain.name>

You'll get this success message:

"Prepare Domain Progress                                   COMPLETED"

Wait for a final AD replication.

You can then check if the schema update successfully by checking the following in ADSIEdit:

• Value of rangeUpper attribute of ms-Exch-Schema-Version-Pt object in Schema NC has changed to 14732.
• objectVersion attribute of Organization container in Configuration NC should be a value of 14247.  
• objectVersion attribute on Microsoft Exchange System Objects container in Domain NC should be unchanged at value of 13040 which is correct.
