As Brian Harry notes in his blog post below, we're getting close to the point where Team Foundation Server Release Candidate and Trial Editions installed earlier this year will start to expire.
We are rapidly approaching 6 months since TFS released. Yeah, that's right - Isn't it amazing how time flies? I've started to see a rash of emails from people who are discovering that their TFS trial Edition and Release Candidate installs are expiring.
Once you've reached that magic day, and there is no countdown leading up to it, you won't be able to access Team Foundation Server. You'll get an error message that reads, "TF30072: The Team Foundation Server trial period has expired or its license is otherwise invalid. Install a licensed edition of Team Foundation Server to continue."
To avoid unnecessary downtime, be sure to upgrade your Team Foundation Server to fully-licensed software as soon as you're able. If you're using Team Foundation Server Release Candidate, you could upgrade to Team Foundation Server Trial Edition while you await your fully-licensed copy. For more information, see Team Foundation Server Upgrade Types.
For eligible Microsoft Partners awaiting their media that was supposed to arrive in the July Toolkit (July Partner Toolkit and Team Foundation Server Disc), those replacement discs should be shipping out today.
UPDATE: Team Foundation Server RC and Team Foundation Server Trial Edition both have a 180-day enforced time limit (aka "time bombed"). When upgrading Team Foundation Server, don't forget to upgrade SQL Server as well. For help determining how long it's been since you installed Team Foundation Server, you can check the date on changeset 1.
