We have multi sites AD environment . We currently have Exchange2010 in a site and trying install Exchange2016 on an another site.
We are getting error for schema-master when we try to /prepschema. That is, the setup on the new Exchange to be server can not reach the schema-master.
We checked AD replication status and they all good.
1. I am thinking of running Schema master prep at the DC which hold the schema master role, is it something advisable?
2. or it it better to move the schema master to the same site as the Exchange to be, only my concern is that what would happen to the existing Exchange 2010?
