Hi all,

here is Our current deployment:

Lync server 2010:

1 edge

1 FE

3 branch sites

1 Monitoring server

Lync server 2013:

3 FrontEnd

2 Edge

2 Mediation

3 Backend

Simple urls are still point to Legacy (2010) servers.

External settings of Edge 2013 servers have been define With different name (Access,WEB and AV) and DNS (internally and externally) is pointing to New 2013 servers (via KEMP and TMG).

ATM 2013 topology is using edge2010 server.

Seems like we have two options for replacing Edge servers,one is Rip and replace and the other one is side by side transition.

We would like to do rip and replace so we can keep old simple urls (so that we dont have to send notice to external partners about Our New Access edge info) and using 2013 edge servers for federation and keep users on 2010 servers,then move them in a controlled way.

What is the best way to do this?

Thanks!
