The Managed Service Account Selection page of the Managed Service Account Migration Wizard specifies the managed service accounts in the source domain that you want to migrate. The managed service accounts can be added from the domain (by using either the object selection dialog box or an include file) or from computers that the Active Directory Migration Tool (ADMT) queries for any installed managed service accounts.
To add one or more managed service accounts from the domain, click Add, and then follow the instructions on the Select Service Accounts page. To add one or more managed service accounts that are installed on computers that you are migrating, click Add, and then follow the instructions on the Select Computers page. To remove one or more managed service accounts, select the accounts, and then click Remove.
