Depends what you mean by "install".
One of the postinstall processes is DLL rebasing, which is crucial for working
Cygwin installation.

I strongly suggest installing anew, as other prople suggested.
You can take a shortcut by pulling the installed.db out of old setup, but take
care.

And yes, backing up your existing installation is still a good idea.
