Hi,

We have LYNC 2010 deployed in 2 site (sit1 & Site2)

Currently all user host on Site1 pool. CMS exist in Site1

we have also mediation role and EDGE role on both site.

we have dial in conference on site1.

Currently public DNS record (for edge and as for reverse proxy) point to Site1.

Certificate Authority for site 1 and and site2 is different. However SAN entries and subject name is same for all certificate and bot CA are public CA.

We have to move all users to site2 pool and will also move CMS to site2 and we have to decommission site1.

What is the step by step process to move users, CMS, Edge server Traffic and Mediation server, reverse proxy?

Hi,

The migration process from one pool to another pool is similar for from Lync Server 2010 to Lync Server 2013.

You can refer to the link below of Migration from Lync Server 2010 to Lync Server 2013

"Inside-out" is the recommended approach to migrate your existing Lync Server 2010 to 2013 infrastructure. For Lync-enabled users, you can utilize the Lync Server Control Panel or Move-CsUser cmdlet to move users from Lync 2010.

The TechNet Library gives a good rundown of what to consider and do for Lync Migration.

Hope this helps. Thanks.
