The Team System User Education team has posted the instructions for upgrading from Team Foundation Server RC to Team Foundation Server RTM, which should tell you something about the pending release of Team Foundation Server, eh?
I can’t stress enough how important it can be to read the instructions. In fact, I recommend doing so now, before you have the bits in hand, so that the overwhelming urge to install them doesn’t compromise your better judgement.
The RTM release of Team Foundation Server is just days away. If you installed the Beta 3 Refresh version or the RC version, you might be wondering how you're going to upgrade to the RTM version. There are two guides available to help you do this. While both guides are available as part of the software package you'll need to download from the Microsoft Web site in order to upgrade, we are also posting them here so you can read ahead. You can view the Upgrading from Team Foundation Server Beta 3 Refresh to the Release to Manufacturing Version (RTM) of Team Foundation Server guide or the Upgrading from Team Foundation Server Release Candidate (RC) to the Release to Manufacturing Version (RTM) of Team Foundation Server guide, to help you plan for your upgrade.
