FYI – the Lync Server 2010 180-day evaluation bits are slated to be available on November 17th which is Lync launch day. You can grab them here on the 17th.
The question I get asked is can you upgrade these bits to production bits at a later point. The answer is yes.
How do I do this?
1) Install Lync Eval RTM bits
2) When the volume license bits for Lync RTM production bits become available, download them and install them overtop of the trial bits.
3) From command line run: “msiexec.exe /fvomus server.msi EVALTOFULL=1 /qb where server.msi = licensed Lync Server media
4) From powershell run: “enable-cscomputer”
Thanks to Andrew Sniderman for the answer!
