Thank you very much for all your replies! I never took a look at sysmerge. I never used it before, because when upgrading to a new OpenBSD version I always took the path that Peter suggested. This time however, because im am only switching architectures and not versions, I figured there should be an easier way. I had hoped for a tool that would simply replace all arm64 binaries with the corresponding amd64 ones. Nevertheless, sysmerge looks quite promising, at least by identifying the files that I will have to take care of.
