Thanks for all the responses!
4.0C is only a hardware upgrade to support Personal Workstation Series
It appears that one can do a straight upgrade from 4.0B to D or E without
stepping. However, an upgrade first to 4.0D or E is required to go to 4.0F
But can anyone suggest if I should just upgrade to 4.0E instead of
4.0D? I'm looking for the last mostly stable version.
Suggestions include:
--have a good backup (a must!)
--install jumbo patch for the new OS version immediately after
--make sure you have enough room in root and /var (if not, this is a good
time to backup, repartition, and restore before upgrade).
--verify your AdvFS domains, if any, with AdvFS verify using the V4.0B
software BEFORE you update
--verify your filesystems first (??? with what, fsck?)
--See the release notes for the subsets that may need to be deinstalled
(AdvFS utilities? ASE?) and reinstalled after upgrade ("installupdate"
should check these and stop)
--Remember to comment out the defragmenter in root cron after you get to D
(???)
--firmware updates may be needed first, which should be part of the OS
CDROM kit (if you've got an EISA bus be sure to re-run the EISA
configuration utility if you update the firmware)
--read and follow the version release notes (and check especially for any
instructions unique to your hardware configuration)
BTW- The machines I'm upgrading are 3 Aspen Alpha 164LX 533, 1 DEC Alpha
250 4/266, and 6 DEC 3000-M400/300 machines... I don't know how that may
impact the "hardware specific cavaets" and/or if firmware needs/should be
upgraded.
also... this MAY be the solution to my previous unsolved problem entitled:
"transfer times 10x difference", which someone else solved with firmware
upgrade and using 4.0D. I upgraded firmware with no fix, but we're running
4.0B. I'm crossing my fingers that this last effort is the key!
