Distribution Groups - Exchange Cross Forest Migration

Hello Experts,

i am during a Cross Forest Migration from Exchange 2013 to Exchange 2016.
I did it with prepare-moverequest script and migrated round about 50 Percent of the Users.
So i have still old mailboxes on the source exchange and migrated mailboxes on the target exchange.

Now i have a Question regarding the Mailgroups.
I have 30 Mailgroups on the old exchange server. How can i migrate them to the new server.
I Think the easiest way is just to create the Distribution Groups on the new server and give them the same mail adress.
Then putting the members to the group. migrated mailboxes and prepared mailuser from script when still not migrated.

Is there maybe a more preferable way to do it? Do i need to migrate the exchange attributes and why?

best regards,
Lukas

For distribution groups, you can use ADMT tool which can migrate groups from source to target along with group members without exchange attributes as ADMT won't migrate exchange attributes
Then simply mail enabled them through exchange management console / eac

Further you have only 30 groups, if ADMT is already not setup, you can do manually as you stated already
