Migration Tru64 4.0D to Tru64 5.1

Migration Tru64 4.0D to Tru64 5.1

Post by Piotr » Thu, 22 Mar 2001 05:44:09



I have twenty Alpha servers (some 1000A, some 4100, some 8200 ...) with
Tru64 4.0D.
I must migrate to Tru64 5.1.

I have 2 choises :
    - install the 5.1 and restore the conf files
    - migrate 4.0D to 4.0F first, and migrate 4.0F to 5.1

I prefer make a new install to make the new servers more "clean".

Your opinions ?

Go to 4.0F then installupdate to 5.1. Less risk.

1. Upgrade of DU4.0D(patch6) -> Tru64 5.1

We are using an Alphaserver 4100 5/466 with a Storageworks 450 RAID Array.
This machine is used for development and testing purposes in order to
support a bespoke application. This application is used by two of our
clients. We (the two clients and ourselves) will need to upgrade the OS very
soon. I am interested to get an understanding of the best (and safest) way
to do this, given that we must be able to support both clients throughout
the upgrade process. I had considered the following;

1) Schedule (only) the upgrade on site - to be managed by the clients.
2) Lease a machine and configuring it so that could be used to support both
clients.
3) Perform the OS upgrade on the original machine.
4) Test the OS.
5) Test the application
6) Fix any problems
7) Deliver the application fixes
8) Give the OK to both clients to perform the OS upgrade and apply any
application patches.
9) Allow a week or so in case there are any major upgrade issues
10) Return the leased machine.

Having never performed an OS upgrade I am obviously concerned about the
implications of the upgrade. Can anyone advise me on the following;

1) What kind of problems might I encounter?
2) Are there any automated scripts for testing the OS after the upgrade?
3) Is the above a gold plated solution?
4) What is the recommended approach?

Any help or advise is much appreciated.

Regards,

Mat.
