Hi,
I need to upgrade one of my clusters from HACMP 5.41 to HACMP 6.1.
Is there an easy + clean way to do it ? Any hurdles I have to anticipate? What should I read - anything I found so far seems to talk only about HACMP 5.x - and looks pretty straight forward.
Thanks and regards

REDHAT-UPGRADE-TOOL(8) redhat-upgrade-tool User Manual REDHAT-UPGRADE-TOOL(8)
NAME
redhat-upgrade-tool - Red Hat Upgrade tool
SYNOPSIS
redhat-upgrade-tool [OPTIONS] SOURCE
DESCRIPTION
redhat-upgrade-tool is the Red Hat Upgrade tool.
The redhat-upgrade-tool client runs on the system to be upgraded. It determines what packages are needed for upgrade and gathers them from
the source(s) given. It also fetches and sets up the boot images needed to run the upgrade and sets up the system to perform the upgrade at
next boot.
The actual upgrade takes place when the system is rebooted, using the boot images set up by redhat-upgrade-tool. The upgrade initrd starts
the existing system (mostly) as normal, lets it mount all the local filesystems, then starts the upgrade.
When the upgrade finishes, it reboots the system into the newly-upgraded OS.

-h, --help

--reboot

SOURCE
These options tell redhat-upgrade-tool where to look for the packages and boot images needed to run the upgrade. At least one of these
