Deleting SCP on Exchange servers...Need Help Please

Hi There,

We have been running Ex2010, Ex2016 & Office 365 Hybrid Environment for two year... Now I am trying to remove ex2010 server. So I will start with deleting the old SCP points.

Now I can see on SCP on two servers:

On Exchange 2016 server:

It has two SCP connectors: ex2010 and ex2016.

On Exchange 2010 server:

It has only one SCP connectors ex2010 .

If I want to decommission Exchange 2010 server and delete SCP for Ex2010 only for now .

Should I run this command only on Exchange server 2010:

set-ClientAccessServer -identity EX2010 -AutoDiscoverServiceInternalUri $null

?

Or I have to run:

set-ClientAccessService -identity EX01 -AutoDiscoverServiceInternalUri $null

on Exchange 2016 server?

Thanks a lot,
ML

Hi @NamlessShelter-6097 ,

Good day!

Based on my knowledge, the SCP is used to locate the Autodiscover service, and it stays in AD which means you could run it on both servers that have joined the domain.
May I suppose the identity, EX2010 and EX01 are the same server? If so you could run either or them.

And you can delete the SCP with ADSI EDIT:

hi Mate,

Thanks for the reply.

The thing is that I want to power off EX01 for 1 week to see any services are still pointing at the old server. So I woud like to delete SCP first.

Should I delete SCP on both Ex2016 and Ex2010 servers?

Thanks

Hi @NamlessShelter-6097 ,

No you don't have to do that, I believe that both of the commends would do the same thing. You could check it after run on EX2010.

And you could also set the AutodiscoverURL of EX2010 pointing to EX2016 to test.

Best regards,
Lou

Hi Lou,

If I run

"set-ClientAccessServer -identity EX01 -AutoDiscoverServiceInternalUri $null" the old Exchange 2010 Ex01 will not have SCP. So it will update and Ex2016 server and ADSI attribute as well. Then, the new exchange 2016 server will have only SCP. Am I correct?

Thanks

So how do I find out if we have CAS Array? We only have one Ex2010 server.

Thanks

Hi @NamlessShelter-6097 ,

You could use Get-ClientAccessArray or use the ADSI EDIT, same path.
If there is no values in the Arrays folder, then there is no CAS Array.

Hi Lou,

I have deleted the old SCP for exchange 2010 successfully without any problems now. I have powered it off the ex 2010 server for now to see if anything still sending to the old Ex2010 server. Ex2016 server is still running hybrid with Offic365 Mails.

My question now is can I power off the old ex 2010 server as long as I can? Or I better decommission it say end of this year?

thanks a lot

Hi @NamlessShelter-6097 ,

My suggestion is to run this for a time like one or two weeks to check if it's totally hybrided without mistakes.

And after that you can simplely decommission Exchange 2010 at any time you want, make sure the data has been migrated to the new server.

Cheers,
Lou
