1) When I attempt to reintegrate, I am getting the following error: Error: Retrieval of mergeinfo unsupported by '...my repo path...'. The research that I've done suggested I need to upgrade my server version of Subversion, but I would like to avoid doing this because of the corporate red tape. Any other suggestions?
What client and version are you using? Recent versions of TSVN, for example, support an easy Reintegrate option, but the server-side has to be at a version to support it. This sounds like a version mismatch related to automatic merge tracking, and that you have a more-recent client and a not-so-recent server. If that's the case, you could try the old-fashioned way of merging ranges of revisions and track merges by hand. Automatic merge tracking isn't going to work unless the server knows about it. Erik
