Many enterprises begin their Office Communications Server deployment with a single Enterprise Edition Front End Server. As usage of the product becomes increasingly mission critical, it is common to move to a load-balanced configuration to provide high availability and increased capacity.

However, a new pool would need to be created and users migrated to this new pool as part of the cut over procedure.
