Hello,
I am at a customer right now, where we are going to migrate from UM 2010 to UM 2013(Full Exchange migration), while doing a Lync migration as well. My question is simply, is there any way to coexist the two UM environments so that an individual user migration can be done?
Scenario;
UM 2010 and Lync 2010 user gets migrated to Exchange 2013 with his UM as well. This user would be a Exchange UM 2013 user, on a Lync 2010 pool. All my UM dialplans are made pointing to the old pool, which would give routing issues as I see it.
Is there a way to automate Things, so when this user is moved to the new Exchange server, then he will still Work on Lync 2010?
Thank you for helping out :-)
Kind regards, Thomas Laursen
