By the way, is the upgrade from 2.1 to 3.1 a non-destructive one, or do you need to reinstall all other software too? And 3.1 should be fully backward compatible with virtually all software and hardware working under 2.1?
Has anyone experienced a headache doing this upgrade?
Been a while since I've done it, but I'm fairly certain it's non destructive. It'll replace your startup-sequence and... I think that's it. Any non-standard files it replaces, the installer backs up to SYS:OLD.
Do a manual backup to be safe, though. It's just a simple copy #? all clone command. And you can even store the backup on the SYS: partition in a subdirectory.
