I have two repositories hosted on bitbucket server where one of them should have been created as a fork of the other, rather than an independent repository (i.e., they share common branches/commits as can be seen in git when the working directory contains the two corresponding remotes). Unfortunately, when I push changes to the "downstream" repository, I can't create pull requests into the "upstream" repository because it wasn't created as a fork (the upstream repo doesn't appear in the drop down box of destination repositories). Is it possible to assign the "downstream" as a fork of the "upstream" after it's been created? I know I can erase the "downstream" and create a new one as a fork (repopulating the git data by cloning the original downstream before erasing it), but my understanding is that would lose all the existing bitbucket meta data like pull requests.
Thanks.
