RTC3 and 4 repos in same client and traversing history across them
One answer
Sadly there is no easy mechanism other than upgrading your V3 system to V4.

basically to get the history without upgrading the old system, you have to use a man in the middle approach.
setup a duplicate level of your existing system, and replicate the streams and workspaces to the new system (snapshots do not replicate)..
then upgrade the man in the middle to the new version, and then replicate again to the new target if it is different.
we had to do that to move a team from a standalone 3.0.1.3 system to a 4.03 corp platform.
we had over 300 streams and workspaces to copy.. I ended up writing a utility to copy all the non workitem data, and my team-mate wrote a utility to copy all the workitem data (attachments, approvals, comments, links) and fixup for the changed workitem numbers.. they left work on Friday using 3.0.1.3 and come into work on monday on 4.0.3 picking up where they left off.. only a couple customized plans didn't get copied over.
