Let's say I have created a SVN feature branch "Feature123" from a release branch "Version1.0", to work on a new feature. I've made some changes in my feature branch and committed them to the repository, but not yet reintegrated the feature branch into the release branch. In the meantime, we also have created a "Version2.0" release branch, for a future release. Now my manager tells me that he doesn't want my feature123 in version 1.0, but in version 2.0 instead.
Is there a way that I can reintegrate my Feature123 branch into Version2.0, even though the feature branch was created as a branch of Version1.0?
You can in Subversion merge from any path to any path - all branches are equal by nature (and your branches have common parent anyway)
