Migrating Multiple Sites and Pools
Topic Last Modified: 2011-04-04
Microsoft Lync Server 2010 supports multi-site and multi-pool deployments. The process of migrating multiple pools from Microsoft Office Communications Server 2007 R2 to Lync Server 2010 requires the following considerations:
After deploying a Lync Server pilot pool and importing the Office Communications Server 2007 R2 pool configuration to the Lync Server pool, you need to define a subset of pilot users that will be moved to the Lync Server pool, and a methodology for validating the functionality of the users.
After deploying an Edge Server in the pilot pool, you need to validate that external users can communicate with the Lync Server pool.
After transitioning the federated routes from Communications Server 2007 R2 Edge Servers to the pilot Lync Server Edge Servers, you need to validate that federated users can communicate with the Lync Server pool.
After moving all the users and non-user contact objects, you need to validate that the Communications Server 2007 R2 pool is empty.
After verifying that the Communications Server 2007 R2 pool is empty, you can then deactivate the pool.
After verifying that all pools are deactivated, and all Communications Server 2007 R2 Edge Servers have been uninstalled, use the Topology Builder Merge wizard to remove the legacy topology from the site. Finally, use Topology Builder to delete the BackCompatSite.
