You don't need to backup and reinstall.  Read the man page for mkswap;
you can create a swap file rather than a swap partition.  I.e.

# fallocate --length 12G /swap
# mkswap /swap

will create a 12GiB file, /swap, that can be used as a swap file.

In order for it to be used by hibernate, I think it must be in
/etc/fstab.  You can probably create it, edit fstab, turn on the swap
file with swapon, and then test hibernate without first rebooting.

I don't know whether hibernate will use both swap files, choose the
larger, or choose the first (or something else).  It might be a good
idea to comment out the fstab entry for the 1G swap partition and turn
it off with swapoff before attempting to hibernate.
