One way to deal:
- Backup your server on a USB drive
- Change drives etc.
- Reinstall 7.2 from CD (if your 3ware raid card is not supported, use software raid native in SME)
- Restore from USB at end of installation
- Reinstall contribs, config files will have been moved across when restoring, so not a big job.
Hope it helps.
