This is not the right way to do things. Emacs-27 is currently not released and liable to be unstable. The jit branch is more so. Updating from an old version (Emacs-24) to an unstable branch is not going to leave you in a good place to debug any issues. First, move your stuff from Emacs-24 to Emacs-26 -- either one you build or a pre-compiled version. If want to try Emacs-27 with the JIT branch, do so from there; there is a reasonably good change that you will have to make no configuration changes between 26 and 27 (jit or otherwise). Install as many packages as you can via package.el. Personally, I modify `package-user-dir' so that it includes the version number and auto-install packages with use-package, but this is probably not necessary. Finally, I would use `git worktree` so that you can have both Emacs-27 and Emacs-27 JIT branch compiled and ready to go. If you are going to live on an unstable Emacs you may find yourself needing to switch periodically.
