This system never was 4.* (began from 5.0-DP2). I have done this before. The best was to deal with this is to create a 5.1 system locally, and deal with all the problems that come up there, transplanting the resulting scripts to the system in question. Your biggest problems are going to be the creation of the /dev, which will need to occur in an rc.local on reboot, replacing the disklabel boot code, and the changes to the conf file for ssh to operate correctly (you will likely need to regenerate keys). If you can't remotely NFS mount a CDROM, a lot of the work is going to be getting access to installation media. -- Terry
