Lync 2013 Migration

Hi

As part of migration to Lync 2013 we are doing side by side migration from lync 2010 to lync 2013. Have created a Lync 2013 Front end server along with the existing topology of one Front end and one edge server. I am moving few users to the Lync 2013 servers and testing. When the user schedules the meeting, it works from inside office but not from outside office. It just simply says error. is there any routing mechanism for the new Lync 2013 front end pool need to be created. Any help is appreciated

You have to look at External WEB Url for Lync2013 server, and make sure you publish that one externally and in certificate

Like if you have Lyncweb.domain.com in Lync2010 and lyncweb13.domain.com in Lync2013 you need to have both domain names present in certificate
