Can I change the /home folder after ubuntu installation? [duplicate]

I had installed Ubuntu 11.10 on a clear 40gb hd, but now i have a 100gb partition that i want to use as a /home folder, is there a problem to simple use fstab to change the mounting point?

I'm thinking to copy/paste all the archives in actual /home folder to this 100gb partition and then change the mounting point in fstab.

Edit: I will not make this because this 100gb partition is ntfs type, so no donuts for me.

Check out the howto: https://help.ubuntu.com/community/Partitioning/Home/Moving

The basic steps are as follows:

1. Setup your new partition.
2. Backup and edit your fstab file (/etc/fstab) to mount the new partition as /media/home (just for the time being) and reboot.
3. Use rsync to migrate all data from /home into /media/home.
4. Edit fstab again so the new partition mounts as /home instead of /media/home but not reboot just yet.
5. Move /home to /old_home and reboot.
6. Delete /old_home.
