I was experimenting with a spare Siemens 9006.3. I found that if I loaded the system with hard drive A, I could install hard drive B and do EXE-UPDAT A1 and BP ALL, and the config of A is now on drive B. Drive B had an older version of Unix without Direct Amo. I thought by doing the A1 update it may have loaded A's Unix, but apparently not. The old root password still works on B, with that I can enter UFAMOS and get into Direct Amo. I was surprised to see the system allowed the database that was originally from a system with an new Unix version to be saved on the hard drive with the older Unix (without Direct Amo). It appears I'd need to do a Unix restore from tape to get to the newer version.
