Afternoon all

I'm stuck in limbo with what to do next in regards to the current server migration issue.

I have been migrating an SBS2007 box to a new Server2012 Hyper-V running Exchange 2013. I have moved all the users over, everything from the old exchange has been disabled in services and now im in the decommission process for the SBS.

I have noticed when uninstalling the Exchange it asks about the OAB role, i fully well know i can just open up ADSI edit and remove this to continue with the uninstall but the last thing i want is my client to loose all of their contacts in outlook!

i don't really know my Powershell that well! and this exchange migration is quite new to me, i would like to know how do i check (from the end users machine) to see which OAB they are currently DL'in from? and to check the information in each of these stores.

I have run the command to do a check on the active OAB's and can see two, one on my SBS and the other on the new exchange. I would like to know how (if possible) to move the current information from the old OAB into the new to prevent me from deleting all the contacts while im trying to uninstall the old exchange.

Might be very vague but if you need more information then please let me know will provide you with information.

Just create a new OAB in Exchange 2013, which may have already happened.
Then delete the OAB in the Exchange 2007 server.

You will need to change the OAB setting on all databases to the new OAB before you delete the old one.

The OAB will not touch the Contacts so it will have no effect there.
