We have been evaluating Lync 2010 Standard edition for more than a year now. It was our intent to roll this out company wide (approximately 250 employees) but other project kept getting in the way. We have a small number of people testing Lync, maybe 10 or so.
Now that Lync 2013 has been out we want to upgrade to Lync 2013 before deploying this to all of our employees. I'd really love to do an in place upgrade, but I don't think that's possible. I'm really looking for the simplest upgrade path for us.
What is the best upgrade path? I don't care if we have to start over as there have been very little customized settings we put into Lync. We're only using it for IM and nothing more.
