The following script will get all the members of an Azure AD group and add them to another group. You’ll just need to know the name of the two groups to make it work.
In the code shown below, the source group will be called Group1Name and the destination one Group2Name.
# Replace Group1Name with the name of your source group and Group2Name with the name of the destination one. Everything else will be done automatically
$Group1 = "Group1Name"
$Group2 = "Group2Name"
$group1ObjectID = Get-AzureADGroup -Filter "Displayname eq '$group1'" | Select objectid -ExpandProperty ObjectID
$group2ObjectID = Get-AzureADGroup -Filter "Displayname eq '$group2'" | Select objectid -ExpandProperty ObjectID
$membersGroup1 = Get-AzureADGroupMember -ObjectId $group1ObjectID -All $true
foreach($member in $membersGroup1)
{
$currentuser = Get-AzureADUser -ObjectId $member.ObjectId | select objectid
Add-AzureADGroupMember -ObjectId $group2ObjectID -RefObjectId $currentuser.objectid
}
Get-AzureADGroupMember -ObjectId $group2ObjectID -All $true
