Migrate OCS 2007 R2 to Lync 2013

I have been tasked to migrate our OCS 2007 R2 server to Lync 2013. There are about 200 clients using basic functionality, IM, VM, Conferencing. I am unable to find a step-by-step guide on how to get started. There are hundred of articles but in bits and pieces. I would very much appreciate if someone can point me on how I can get started. It would be nice to get a solution which meets high availability and DR.

Thanks for your help.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Microsoft has migration guidance for moving from OCS 2007 R2 to Lync 2013.


If your OCS 2007 R2 is not highly available then you'll also need to follow the "planning" guidance, not just the migration guidance, since you aren't "just" migrating anymore, but are adding new components. Basically go through the planning first so you know what components you'll want for HA and then follow the migration guidance to move the actual content (databases, etc) to the newly designed topology.  But if you try to ad-hoc it, you'll end up in the weeds.
