Exchange 2016 OAB Generation server

Hi,

Recently I upgraded windows 2008 DOmain controller to Windows 2016 DC, also migrated Exchange server from 2010 to Exchange 2016. after migrated i saw that Offline address book generation server is 2008 DOmain controller, can i change OAB gen from 2008 to EXchange 2016 rather then generating a new address book.  As we are going to demote the WIn2k8 domain controller after some time.

If yes, please let me know the steps.

please advice.

you need to point your DBs to 2016 exchange server OAB only for all databases it hosts
The OAB must be already there for exchange 2016, you simply need to point there

This  i have already did that... but when  running a command to see

Get-offlineaddressbook | fl

there its showing oAB generation server is windows 2008 domain controller , that  i have to change to Exchange server 2016....
have you moved all your arbitration mailboxes to exchange 2016?

If not, do that, one system mailbox is responsible for OAB generation

https://blogs.technet.microsoft.com/exchange/2013/01/14/managing-oab-in-exchange-server-2013/

here is additional reading..
https://blogs.technet.microsoft.com/exchange/2012/10/26/oab-in-exchange-server-2013/
If I am not mistaken Exchange 2010 and higher version of Exchange deals with Offline addressbook in different ways.
It is re-engineered in Exchange 2013 and highrer version.
When you upgrade an Exchange 2010 server to 2013 a new address book will be created by the installation with Originating server Exchange 2013.
I think the same way it should be in Exchange 2016.
In Exchnage 2010 addressbook is generated in mailbox server and copied to CAS server for distribution using DFS.
But Exchange 2013 and higher versions it is stored in system mailbox.  
I think it is better create a new Address book and delete the old one.

yes & also users are still not able to update the OAB
This is your DC not Exchange server. You cannot change it is picked up by Exchange for generating OAB.

but if we demote this Server after few days.. there will be a issue for Offline address book.. & transfer the FSMO role to Win20016 DOmain controler

When you move FSMO roles Exchange will connect to 2016 automatically.
