(The production server cannot go down > for more than a few seconds.) 1. dump / restore (probably not feasible on 4.x since there's no snapshots) 2. do a minimal install on the new box and rsync everything over from the live box 3. use bsdtar and an ssh tunnel to copy everything over from the old box 4. install dar and use that to archive everything, transfer the archive over to the new box and restore it there 5. buy a harddrive cloner (only feasible if the box can be done for a while) 6. dd over an ssh tunnel may also work I've used a variations of 3 (giant tarball of the whole drive burned to CD) and 4 (giant dar archive of the whole drive copied around the network) with great success. -- Freddie Cash fcash@ocis.net
