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.
