Upgrading Office Communicator Server 2005 to Lync Server 2010

Hi,

My company is in the process of upgrading from Office Communicator Server (2005) to what is now known as Lync Server 2010.

As far as I know the process is not straight forward. I've been told that I need to first upgrade from 2005 to 2007, and then to 2010.

Is this true? Also, is there a way to migrate settings/contact information from the 2005 version to 2010?

Thanks

well. you are right. you should migrate to 2007 then 2010 (or 2013 which is the latest!)

you can do a cut over install from 2005 to 2010 (means turn off 2005 one day and turn on 2010). by doing this way, all settings/contact will not be migrated.

if you only have a handful of them, then this might be the best option.
Though this method is not microsoft support.

====================

you can see the microsoft support LCS 2005 to Lync 2010 migration strategy for more information.

in short, you are right, there is no straight forward process.


NOTe: Lync 2013 is the latest
