I'm using ADMT (Active Directory Migration Tool) to move users from a child domain into a parent domain. Since one of the requirements is to use a SQL Server I'd like to point it to one that already exists within that forest.
However, that SQL Server has an instance running that supports one of the main information systems at the site, and is therefore precious. Would ADMT require that I start a new instance? Would it be able to use the existing instance that the information system is using? What are the risks involved here if any?
Additionally, once the migration is complete, do I need to keep ADMT (or the SQL Server if I install a local one) installed? I'm assuming the answer to this is no, but I can't find it anywhere in the documentation.
