Question : OCS - Exchange install order?

We are planning on upgrading both our older LCS 2005 server and Exchange 2003 server to the latest versions.  Is there a particular order those should be installed in or does it matter?  Would it be ok if we upgraded OCS first and then Exchange a month or so down the road?

Answer : OCS - Exchange install order?

Two different projects.  You can do them in either order, but I would do whichever gives you the most functionality first.  For some that will be the new OWA.  Others, may need Live Meeting more.  Your choice.
