V5.5-2H4 and V6.2 in a cluster?

The Question is:

Can VAX VMS v5.5-h4 exist in a cluster with AXP VMS 6.2 ? Is this supported and under what rules ?

The Answer is:

This is a supported configuration as a migration only. To minimize downtime, VMSclusters support the concept of a rolling upgrade. Successive versions can interoperate in a migration mode until the rolling upgrade can be completed. The OpenVMS Alpha V6.2 is a successive version to OpenVMS VAX V5.5-2H4.

From the OpenVMS SPD; 

           Migration support means that Digital has qualified the two
           architectures and versions for use together in configura-
           tions that are migrating in a staged fashion to a higher
           version of OpenVMS or to Alpha systems. Digital will answer
           problem reports submitted about these configurations.
           However, in exceptional cases, Digital may recommend that you
           move your system to a warranted configuration as part of the
           solution.

Note that Digital does not support the use of more than two versions of OpenVMS software in a VMScluster at a time.

Digital recommends that all Alpha and VAX systems in a VMScluster run the latest version of OpenVMS.
