To ensure you are merging the appropriate Active Directory objects, you should review, and if necessary, modify the list of merge operations that the wizard is ready to perform. You can review and modify merge operations from the wizard or from the .csv file that you exported.
Caution You should review and modify merge operations before you start the merge process in Active Directory. Once the merge process is complete, you can not undo the operation.
The amount of time it takes to review and modify merge operations depends on the size and number of duplicate objects in Active Directory. It may take a significant amount of time to review and modify the merge operations. You may want to export a list of merge operations that the wizard has found and then, at a later time, run the merge process.
