Migrate the URLs to Exchange 2016 servers or replace Exchange 2013 servers in the CAS load balanced cluster with Exchange 2016 servers (both Exchange 2016 and Exchange 2013 can coexist in the same CAS load balanced cluster).Install certificates on the Exchange 2016 CAS servers.Configure Service Connection Point using Set-ClientAccessService -AutodiscoverServiceInternalUri on each Exchange 2016 CAS server.Install Exchange 2016 servers (this will prepare AD and prepare the domains automatically but you can do these as separate tasks if done by a different team etc).Ensure that any Exchange 2010 servers are upgraded to SP3 UR 11.Upgrade all Exchange 2013 servers to CU 10.You can use the below process to do an Exchange 2013 to Exchange 2016 migration which is almost the same as migrating from Exchange 2013 to Exchange 2013: To Exchange 2016 and Exchange 2013 and Exchange 2016 can exist in the same load balanced CAS array. However the process will be very similar to introducing new Exchange 2013 servers into your environment as Exchange 2013 can proxy requests

That's the link for upgrade from Exchange 2010 to Exchange 2013.Ĭurrently the Exchange Deployment Assistant has not been updated to include Exchange 2013 to 2016 migration steps. Thanks for your replay Sathish, but I was looking for some thing a little more official as (v=exchg.150).aspx.
