Migrate Users from OCS 2005 to Lync Server 2010

I am in the process of deploying Lync Server 2010 into my environment. We are currently running the following.

DC1 - Windows 2008 R2
DC2 - Windows 2008 R2
Domain Functional Level Windows 2008 R2
Exchange 2003
Microsoft Office Communicator 2005
Desktop - 90% Windows 7 / 10% Windows XPSP3

I have been running communicator 2005 for 2 years now and would like to move everyone over to Lync. I'm not utilizing Lync to its fullest yet, I am just wanting to use it internally as we do the 2005 version. Everything is installed and all services are running. The problem I am having is moving the users from the 2005 pool over to the new server pool.

I can see the users under Lync 2010 with Legacy mode, and it tells me that it is enable for Lynch 2010. I just can not sign in under the client side.

I read a post somewhere that if the user that you are trying to move over is part of the Admin Group that there are certain steps you have to take, but the post did not tell you what those steps were.

Any help would be appreciative.

You cannot move users directly from LCS 2005 to Lync 2010 as it's not a supported migration path.  Normally you'd have to migrate users from LCS to OCS, then form OCS to Lync.

In order to hop directly to Lync you'll have to disable each user account in LCS and then re-enable each account in Lync.  This process will not bring any of the LCS database content over so user's will lose their contact list, but these typically can easily be recreated by the users.  Additionally the way that Lync is designed it's better to use the search functions then to add a ton of users to the contact list anyway, so starting fresh can be a good thing for correctly using Lync as it was intended.
