DEC 4.0f to HP AIX 5.1

[CiaranG]

Hi

Has anybody migrated apps from DEC Digital Unix 4.0f to HP AIX 5.1 on a DEC and what problems were encountered, or do you know of a good web site that could point me towards the problems.

Thanks

Not sure what you are talking about ....

I understand that AIX is IBM's version of Unix. But I never heard of HP AIX.
Do you mean HP-UX?
But currrent versions of HP-UX are 9,10,11 ...
Not sure whether there ever existed an HP-UX 5.1 ....

And I think your DEC machine has an Alpha processeor, and there are few operating systems that may run on this.
The best I can guess is that you want to upgrade to Tru64 Unix V5.1, formerly sold by Compaq and nowadays by HP.
Tru64 V5.1 is the successor of Digital's/Compaq's OSF V4.0x.

hope this helps ...

We looked at upgrading some Alpha servers from Digial UNIX v4.0F to Compaq (now HP) Tru64 5.1a (and hence the applications) over a year ago. To take advantage of the new AdvFS and the new "special device file" names, all filesystems would have to be rebuilt (ie backup the data, destroy the old AdvFS domains, create them again and restore the data). With such a major rebuild we concluded we would prefer to start with a fresh installation of Tru64 5.1a (also we found out there is no upgrade path from v4.0F to v5.1a without going to v5.0a first). So for the applications, we planned to do fresh installs of the software and restore the data from tape. The major issue was the amount of down-time that would be required, particularly for our live/production systems.

The basic upgrade/install information we found on HP's website.

I hope that helps. (For further information, please post specific questions)

I migrated from Tru64 5.0a to Tru64 5.1. I am using UFS filesystems only. Following steps were taken:

Backup root, /usr, /var and all other filesystems
Backup /var/adm/lmf directory, /etc and application root
Installed Tru64 5.1 afresh
Installed PatchKit
Restored Application
Restored /var/adm/lmf, /etc/passwd, /etc/fstab, /etc/profile, /etc/hosts, /etc/sysconfigtab file

Migration was successful and took only 4 hours. Before you proceed confirm that your current ver of application is supported in Tru64 5.1.
