title: Copy users from multiple AD-groups to new AD-Groups using Powershell
body: <p>I am trying to copy multiple users from a pair of 2 or 3 groups to one new group.
  There are 30 groups which needs to be moved to 10 new groups.</p>
  <pre><code>Example:
  Oldgroup1, Oldgroup2, Oldgroup3 &gt; NewGroup1
  Oldgroup4, Oldgroup5 &gt; NewGroup2
  </code></pre>
  <p>I am thinking of foreach loop but can not figuer out how to bind multiple old groups to new group as members from old groups can be diff.</p>
