Para realizar la migración desde OCS 2007 R2 para Lync Server 2010 tenemos que tomar en cuenta los siguiente:
· Es valida la utilización de Hyper-V como solución de virtualización y/o servidores físicos, ambos escenarios son soportador por Microsoft. Nota es recomendable que los servidores Edge Server de Lync sean físicos pero están soportados bajo un escenario virtual.
· El nivel funcional del dominio soportado por Microsoft Lync Server 2010 es 2003 Nativo como mínimo
· Todos los controladores de dominio deben estar con Service Pack 2 (SP2) de Windows Server y/o Windows Server 2008 R2 SP1
· Disponer de un ambiente de coexistencia para alojar los roles y servicios de Microsoft Lync Server 2010 (servidores virtuales y/o físicos), no se puede instalar Lync Server sobre los servidores OCS 2007 R2
· Pasar en el entorno actual de OCS 2007 R2 el Best Practice Analyzer de Lync

· Realizar un Legacy Backup de la infraestructura actual de OCS 2007 R2

· Desplegar en los servidores OCS 2007 R2 los updates necesarios para realizar la coexistencia con Microsoft Lync Server 2010, así como los respectivos comandos Powershell para realizar la convergencia de los roles a migrar:

· Se debe disponer de las medias de Microsoft Lync Server 2010 dependiendo así como las respectivas CAL (Licenciamiento) para los usuarios móviles y de voz empresarial. Microsoft Lync Server 2010 en su versión Enterprise da a la solución a implementar alta disponibilidad, tolerancia a fallas y balanceo de carga este ultimo basados en DNS Round Robin pero es soportable con balanceadores de carga hardware.
· Los servicios de Front End, Back End y Edge Server se configuraran en clúster utilizando como sistema operativo Windows Server 2008 R2 Enterprise, si vamos a contar con un ambiente de alta disponibilidad, no aplica para la versión Standard Edition.
· Contar con los puertos y configuración a nivel de DNS tanto para los clientes internos y externos a fin de garantizar el funcionamiento de todos los roles y servicios e Microsoft Lync Server 2010:
