2.3 Mixed-Version Support in OpenVMS Cluster Systems
HP provides two levels of support for mixed-version and mixed-architecture OpenVMS Cluster
systems: warranted support and migration support.
Warranted support means that HP has fully qualified the two specified versions coexisting in
an OpenVMS Cluster and will address all problems identified by customers using this
configuration.
Migration support means that HP has qualified the versions for use together in configurations
that are migrating in a staged fashion to a newer version of OpenVMS VAX, OpenVMS Alpha,
or OpenVMS Integrity servers. Problem reports submitted against these configurations will be
answered by HP. However, in exceptional cases, HP may request that you move to a warranted
configuration as part of the solution. Migration support helps customers move to warranted
OpenVMS Cluster pairs. For the minimum version supported for an upgrade to OpenVMS
Version 8.4, see Section 4.3.1 (page 84).
