What are the major management differences in features between Lync and OCS?

Lync introduces a new management server for Microsoft's UC and collaboration platform. The server is called Central Management Server, and it removes settings for Live Communications Server and Office Communications Server from Active Directory so customers don't have to change the AD schema. The new server is meant to make deployment less daunting.

Are there new administrative tools?

Yes, including Lync Server Control Panel, used to administer Lync server, that replaces Microsoft Management Console for this task.

Also included is role-based access control, which includes 11 preset roles that define and limit administrative rights for specific, routine tasks.
