Swap partitions between /home and /var

    I have a server with 2TB (Raid, 2x2TB), and this partition schema

    / => /dev/md2 - 20GB
    /home => /dev/md3 - 1.8TB

    This is a ISPConfig server, so we need many space in /var and almost nothing into /home, so i think that the best way to do this is put /home in /dev/md2 and /var into /dev/md3

    My fstab is this:

    # <file system> <mount point> <type> <options> <dump> <pass>
    /dev/md2 / ext4 errors=remount-ro 0 1
    /dev/md3 /home ext4 defaults 1 2
    /dev/sda4 swap swap defaults 0 0
    /dev/sdb4 swap swap defaults 0 0

    Which is the best way to do this? I think move /home contents to /homeold, remove from fstab, umount and now copy from /homeold to /home, and then change /var name (i dont have enough space to do the copy), mount new /var and move content, is this correct?

    Also, i need to stop all server services to avoid errors (mysql, apache, mongodb, named, etc), any fast way to do this? Or maybe i should restart in rescue mode to do this?

    Maybe another way is a full change between / and /home, i mean, put / in /md3 and /home in md2, is this possible only by edit fstab and reboot?

    Thank you sou much,

    well, some people use rsync as a cp replacement :) it's not a bad idea actually :)
