I haven't done anything like it. Theoretically speaking, all you
need is a bit of disk space for the undo tablespace. Quite a bit
actually, if that database is even remotely similar to being active,
but few hundred gigs is cheap today, at least when I don't have to pay
for them. Five days is outrageous. My UNDO_RETENTION is 3600 seconds
or 1 hour. You'll have problem converting 5 days in seconds. Please,
let us know how does the adventure end.
