At this time, we had 3 different domain name ie :
1. abc.co.id (External domain)
2. ho.abc (internal domain) at Headquarter.
3. abc.id (internal domain) on the entire estate.
We are planning to move the entire client and to migrate all existing servers in domain ho.abc into abc.id including SAP Production, Development, Ides and SOLMAN Server.
Please help what should be prepared for the implementation of the above considering SAP Installation Server domain method installation...
