You can have as many Cygwin installations on a single machine as you can
tell apart and they are all independent… so yes, provided you can ensure
that the currently in-use installation is not modified while you do this
(i.e. all work directories are separate mount points) and you have
enough space available for a duplicate installation, you can clone it to
a second root (*), run setup to update that while you keep using the old
installation, then switch the active installation by swapping the roots
at some convenient time.

(*) You must ensure that the DACL transfer unchanged and that you don't
copy files through symlinks or from outside the installation root.


Regards,
Achim.
