Move-DominoGroupToAD: How to migrate SMTP addresses with groups

Article
04/04/2008

When attempting to migrate groups from Lotus Notes to Exchange 2007 with the Transporter for Lotus Notes, you may notice that Groups that contain SMTP addresses (non Exchange or Notes users) are not migrated with the group. I became aware of this issue recently when working with a customer and wrote a script to assist in getting these SMTP addresses migrated over cleanly.

So in the first screenshot we see a group in Domino that we want to migrate. By default the addresses highlighted below will not be migrated to AD.

Move-DominoGroupToAD1
Above: The circled users will not be migrated to AD unless the contacts are created beforehand.

Enter Move-DominoGroupToADWithSMTP.ps1:

So the solution is to create a powershell script to come along beforehand and create the contacts. What we risk here is that the contacts will not be created and replicated in the time it takes to run the script, so we tell the script a Global Catalog Server to point to. In the first stage we use this server to write the contact to. In the second stage we call MoveDominoGroupToAD which expects the contact to be there.

In cases where we cannot do this or encounter problems with Move-DominoGroupToAD not detecting contacts in Active Directory, we can use the –CreateContactsOnly switch to create the contacts. Once these contacts replicate throughout Active Directory, we can continue on with the next step of running Move-DominoGroupToADWithSMTP.ps1 or just call Move-DominoGroupToAD directly.

The Script:

# Move-DominoGroupWithSMTP.ps1
#
# Written by Casey Spiller
#
#
# This script will move Domino Groups to Active Directory while preserving SMTP Addresses by
# creating contacts in AD for these users. By default Move-DominoGroupToAD will drop SMTP
# addresses if they do not already exist in AD.
#
# For troubleshooting, please locate the transcript of the script which should be located
# in your My Documents folder (by default).
#
# Known issues: If a user has an SMTP Address on a Domino Group that is also the SMTP Address used
# of a MailUser, we will drop this address. Search the transcript for "SKIPPING" to locate any
# MailUsers who were dropped.
