Migration Phases
Topic Last Modified: 2011-05-05
In Microsoft Lync Server 2010, you define sites on your network that contain Lync Server 2010 components. A site is a set of computers that are well-connected by a high-speed, low-latency network, such as a single local area network (LAN) or two networks connected by a high-speed fiber optic network.
A Front End pool is a set of Front End Servers configured identically, that work together to provide services for a common group of users. A pool provides scalability and failover capability to your users. Each server in a pool must run an identical server role or roles. A Standard Edition server, designed for small organizations, also defines a pool and runs on a single server. This enables you to have Lync Server functionality for a lesser cost, but does not provide a true high-availability solution.
The following phases describe the process of a pool migration from Office Communications Server 2007 R2 to Lync Server 2010. For multiple sites containing multiple pools, each individual pool should follow this phased approach.
Phase 1: Plan Your Migration from Office Communications Server 2007 R2
Phase 7: Add Lync Server 2010 Edge Server and Director to Pilot Pool
Important
This sequence is designed to minimize coexistence and interoperability issues during migration. Implementing Lync Server 2010 in a different sequence is not supported.
