Hello Guys,
The below is our environment:
Two domains, resource.org and forest.org is within in the same forest.
Forest:forest.org
Resource Domain: resource.org
Exchange server is running on resource.org currently. Now, we would like to extend the Exchange 2010 SP3 schema to the AD, the below is the steps we will use:
1. run setup /prepareschema in forest.org domain controller
2. run setup /prepareAD in forest.org domain controller
3. run setup /preparedomain:resource.org in forest.org domain controller
4. run setup /preparealldomains in forest.org domain controller
Are the above steps corrected to extend the schema in our active directory environment?
After that, we will follow the below order to upgrade the exchange:
1. Upgrade the SP3 on Client Access/Hub transport servers
2. upgrade the SP3 on Mailbox servers
Thanks,
Exchange Admin
