has anyone upgraded HACMP from version 4.4.0 to 5.2.0 on AIX, can you
covert from version 4.4.0 or do you have to go through an interim
version, or is it best to just install HA 5.2 and start from scratch?
look into the doc for HACMP 5.2, there is an example of migrating from
previous version. In your case you'll need to go thru
snapshot/uninstall/install/recover snapshot....
