I recommend "do". I had success with this method with my own repositories. Now, I don't know what Nicolas' business requirements are with regard to the immutability of old data; my repository was for a personal project which was being migrated to Google Code and being split out of a larger monolithic repository. I continue to find it very valuable that the entire history of the project works correctly within a single repository. > The amount of time you are going to spend trying to cross migrate old build > environments is expensive, fragile, and requires polluting your history to > generate a new, and misleading one, pointing to the correct SVN server. No, the editing should change the absolute external URLs to relative ones, thus no longer pointing at any specific server, rather just using the current server, whatever address it may be known as.
