disk space shortage, how to migrate to LVM?

Hello

I'm working on AIX 6.1. I inherited something I do not know and now I need to bring it into the line.

# df -m
Filesystem MB blocks Free %Used Mounted on
/dev/hd4 | 256.00 | 87.09 | 66% /
/dev/hd2 | 4608.00 | 82.45 | 99% /usr
/dev/hd3 | 256.00 | 212.34 | 18% /tmp
/dev/hd1 | 256.00 | 1.95 | 100% /home

[cut]
/dev/lv02 | 65024.00 | 60709.92 | 7% /home/users
/dev/lv03 | 65024.00 | 65001.13 | 1% /temp

Now you know why I'm asking of some help.
I'm running out of space on /dev/hd* :|

I have plenty of free space on other drives so I can set up few more LVMs.
Is there any easy way to migrate my files from running-short filesystems to LVMs?

I think that I should prepare lvm, copy all files from such fs and then modify /etc/filesystems to point new disk space for a mountpoint.
Am I correct?

Is there some magic command for such copying?

Do I have to reboot to check whether it works?

Best regards
michael

fdformat

FDFORMAT(8)						     Linux Programmer's Manual						       FDFORMAT(8)

NAME

       fdformat - Low-level formats a floppy disk

SYNOPSIS

       fdformat [-n] device

DESCRIPTION

       fdformat  does  a  low  level  format on a floppy disk.	device is usually one of the following (for floppy devices, the major = 2, and the
       minor is shown for informational purposes only):

	      /dev/fd0d360  (minor = 4)
	      /dev/fd0h1200 (minor = 8)
	      /dev/fd0D360  (minor = 12)
	      /dev/fd0H360  (minor = 12)
	      /dev/fd0D720  (minor = 16)
	      /dev/fd0H720  (minor = 16)
	      /dev/fd0h360  (minor = 20)
	      /dev/fd0h720  (minor = 24)
	      /dev/fd0H1440 (minor = 28)

	      /dev/fd1d360  (minor = 5)
	      /dev/fd1h1200 (minor = 9)
	      /dev/fd1D360  (minor = 13)
	      /dev/fd1H360  (minor = 13)
	      /dev/fd1D720  (minor = 17)
	      /dev/fd1H720  (minor = 17)
	      /dev/fd1h360  (minor = 21)
	      /dev/fd1h720  (minor = 25)
	      /dev/fd1H1440 (minor = 29)

       The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for-
       mat has not been autodetected earlier.  In this case, use setfdprm(8) to load the disk parameters.

OPTIONS

       -n     No verify.  This option will disable the verification that is performed after the format.
