It will not merge the old /home folder, instead, it will replace it.

What I would do is:

  1. make a good backup of your server.
  2. sudo su (or login as root).
  3. mount the new drive (with the correct fstab entry: UUID=[drive uuid] /home_new ext4 defaults 0 0) to /home_new.
  4. sync the old home folder to the new home folder: rsync -av /home/ /home_new/.
  5. rename the old home folder: mv /home /home_old.
  6. change the fstab entry to mount the new drive to /home ( UUID=[drive uuid] /home ext4 defaults 0 0).
  7. Reboot your server. Now your new drive is mounted at /home with all of the original home contents, and your old home folder is accessible at /home_old.

Once you are comfortable, delete the old home folder.

If you run into problems, login as root, unmount /home, comment out or remove the fstab entry for the new drive, rename /home_old to /home and reboot.

This gives some hardware independence, especially when working on a cloud where you can add and move devices as needed.

lsblk -o name,uuid

Use the uuid corresponding to the device and drive name of your convenience.

edit /etc/fstab
UUID="d52669e4-b4ed-4623-b69c-b27ea80f740e"     /drive3    ext4    rw,user,exec 0 2

Can not be afraid of data loss of the first disk?

@Bhargavi,

I think you can do it by using any graphical disk management utility like Gparted or any other, that you need to find out..
