boot disk upgrade

[Giuseppe Sacco <giuseppe@eppesuigoccas.homedns.org>]

hi all,
I would like to replace the main disk I use on the SGI O2. /dev/sda is currently a 9Gb scsi disk, while I would like to replace it with a 18Gb.

Is there any way to copy all data from the old one to the new one?

Thanks,
Giuseppe
