    I have a identical spare second drive available to install 5.2 onto.

    After reading up the alt_disk_install, I'm not sure whether it will like
    installing an older operating system. Also not sure if I should use smit
    alt_mksysb or clone the rootvg.

    What you'd basically do is install aix 5.2 to your other hdisk and then use bootlist -m normal hdisk0 hdisk1 ... where hdisk0 is aix 5.3 and hdisk1 is aix 5.2. When the system reboots it will attempt hdisk0 first, etc so in this case you'd boot aix 5.3. To change the boot order simply use bootlist -m normal hdisk1 hdisk0 ... to boot aix 5.2 first.
