Can we migrate to a new TFS process template and keep history?

Question

We are currently using TFS 2008 with the Scrum for Team System template from Conchango, with a few minor tweaks. We are looking at upgrading to TFS 2010 and we are considering moving to the MSF for Agile template.

What is the best way to move to a new process template and keep history? I'd like to be able to create a new team project on the TFS 2010 server, get everything checked-in, and move our source to the new project. It would be nice if we could somehow keep the check-in comment history and possibly even be able to navigate back to the work item history associated with a changeset in the old project. I'd even be willing to migrate the old project as-is over to 2010 and then move the source to a new project, retaining the old project with work items only in 2010.

Has anyone gone through the process that can over some advice?

Answer 1

We have been through this painful process. Here is some useful information:

1. Yes we used latest release of TFS Integration platform.
2. This blog is your friend for TFS Integration platform.
3. Take a look at mapping xml files here
4. Refer this forum. It has lot of good information.
5. Also see "Upgrading your Process Template in Team Foundation Server" and "Process Template Upgrade #3 – Destroy all Work Items and Import new ones".

Just in case anyone else comes here, I posted some step by step instructions on how to do this (for different templates though) here.
