Non-Rolling Software Upgrades
A non-rolling upgrade allows you to perform a software upgrade from
any previous revision to any higher revision or between operating system
versions. For example, you may do a non-rolling upgrade from SGeRAC
A.11.14 on HP-UX 11i v1 to A.11.16 on HP-UX 11i v2, given both are
running the same architecture.
The cluster cannot be running during a non-rolling upgrade, therefore it
is necessary to halt the entire cluster in order to perform the upgrade.
The next section describes the steps for doing a non-rolling software
upgrade.
