Choose to test or migrate The Group Mapping and Merging Wizard begins by allowing you to select whether you want to test the merging or actually do the merging of groups. Select the Test The Migration Settings And Migrate Later option to run the merge in Test mode or choose the Migrate Now option to actually perform the group merge operation. Testing prior to running the actual merge is recommended.

Select the domains The Domain Selection dialog box next prompts you to select or enter the names (DNS or NetBIOS) of the source and destination domains (if the destination domain is the forest root, you must provide the DNS name).

Select the groups In the Source Group Selection dialog box, you select the groups to merge from the source domain into the group in the destination domain. To do this, click Add, click Advanced, and then click Find Now, which will provide the list of groups that you can merge. Choose the groups to merge, and then click OK twice to add the groups.

Choose the target group Next, you must select the target group into which to merge the groups from the source domain, as shown in the following screen. Type in the name of the target group or click Browse to select a group.

Select the OU You next must select the OU in which the target group will reside.

Specify group options The Group Options dialog box for merging the groups, as shown in the following screen, enables the copying of user rights (selected by default) and the migration of the group SIDs (by adding the SIDs from the groups in the source domain to the SID history of the target group in the destination domain) during the merge process.
