Swap partition or file used by most modern operating systems, including Linux operating systems. This space on a disk in which the system can write portions of memory. Usually, this is a dedicated partition, but it may also be a swapfile.

Linux Move swap space from one location to another location
There is no command or an easy method exists that allows you to move swap space from one location to another. You can turn off the current swap space with the swapoff command in the original location. For instance:
# swapoff /dev/device
Examples
I am going move /my-swap-file to /foo-swap-space location as follows:
# swapoff /my-swap-file
Verify it with the following command:
# swapon -s
Next create a new swap space with the mkswap command. In this example I am creating a new swap file called /foo-swap-space with 4GiB size:
# dd if=/dev/zero of=/foo-swap-space count=4 bs=1GiB
Set up permission:
$ sudo chmod -v 0600 /foo-swap-space
$ sudo chown -v root:root /foo-swap-space
$ ls -l /foo-swap-space
Run the following mkswap command to set up Linux swap area using a file:
# mkswap /foo-swap-space
Activating a swap space by typing the swapon command:
# swapon /foo-swap-space
