Exchange 2007/2010 mixed environment. We have a business unit with 100 populated DEV groups, and they now want 100 QA groups created with the same members (new group name is the same as the old group name, with "DEV" replaced by "QA"). I have the new empty groups created. How can I dump out the membership of an old group to an array and use the array to import them to the corresponding new group. I have a CSV file matching old group name to new group name.

Hi, How is the issue now?Xiu Zhang TechNet Community Support

Yes, that command did the trick. Thanks!
