Q&A: What "Titanium" Will Mean for End Users and IT Pros. "Titanium is being built on the same code base as Exchange 2000, and therefore will use the same storage engine that is currently in Exchange 2000. Titanium will be a smooth upgrade for our customers. We are continuing to make long-term investments to develop our next generation messaging platform, called Kodiak, around Microsoft’s vision for unified data that will first appear in "Yukon," the codename for the next release of SQL Server. It will be several years before this technology is ready to be a mainstream upgrade for our current customers. And I think it’s really important that our Exchange customers know that, with future versions of Exchange, we are not going to require e-mail administrators to become database administrators."
