yes it is possible to do it directly from 5.3 to 7.1 - IF you are absolutely sure that your applications are supporting the new AIX level and all your firmware is up to date - please see
here.
If you use SAP than this is rather questionable as it doesn't only matter on which version you actually are, but as well in which order you might have application patches installed - some patch levels - even when only intermittently installed - can be migrated to 6.1 or 7.1, others cannot.
Additionally, I personally would never even try to do an AIX version upgrade with imported VGs.
If you have a strict separation from application data and OS data, than it might be a lot easier and faster to reinstall the OS from scratch and reimport the VGs. In my company we have a lot of inhouse software that only runs on specific OS versions per package - cleaning up a box, upgrading in place and than installing the new packages takes approx 3x the time it takes me to export the DBs / apps, than install the OS from scratch and than install the new versions.

Hi all,
I have this weird notion that upgrading the TL does not cause the machine to wipe, but upgrading a major version (from aix 6 to 7) means it's actually a fresh install and will wipe the date and i have to install the software again (TSM server, for instance).

NAME
native - native branded zone
DESCRIPTION
The native brand uses the branded zones framework described in brands(5) to run zones installed with the same software as is installed in
the global zone. The system software must always be in sync with the global zone when using a native brand.
SUB-COMMANDS
The following native brand-specific subcommand options are supported in zoneadm(1M).
attach [-u] [-b patchid]...
For native zones, zoneadm checks package and patch levels on the machine to which the zone is to be attached. If the packages/patches
that the zone depends on from the global zone are different (have different revision numbers) from the dependent packages/patches on
the source machine, zoneadm reports these conflicts and does not perform the attach. If the destination system has only newer dependent
packages/patches (higher revision numbers) than those on the source system, you can use the -u option to update the attached zone to
match the -revision packages and patches that exist on the new system. With -u, as in the default behavior, zoneadm does not perform an
attach if outdated packages/patches are found on the target system.
For native zones, one or more -b options can be used to specify a patch ID for a patch installed in the zone. These patches will be
backed out before the zone is attached or, if -u was also specified, updated.
install [-a archive] | [-d path] [-p] [-s] [-u] [-v] [-b patchid]...
The native brand installer supports installing the zone from either the software already installed on the system or from an image of an
installed system running the same release. This can be a full flash archive (see flash_archive(4)) or a cpio(1) or pax(1) "xustar" ar-
chive. The cpio archive be compressed with gzip or bzip2. The image can also be a level 0 ufsdump(1M), a path to the top-level of a
system's root tree, or a pre-existing zone path.
With no options the zone is installed using same software as is running the global zone.
To install the zone from a system image either the -a or -d is required. Either the -u or -p option is also required in this case.
-a archive
The path to a flash_archive(4), cpio(1), or pax(1) "xustar" archive, or a level0 ufsdump(1M), of an installed system. cpio archives
may be compressed using gzip or bzip2.
-b patchid
One or more -b options can be used to specify a patch ID for a patch installed in the system image. These patches will be backed
out during the installation process.
-d path
The path to the root directory of an installed system. If path is a hyphen (-), the zonepath is presumed to be already populated
with the system image.
-p
Preserve the system configuration after installing the zone.
-s
Install silently.
-u
Run sys-unconfig(1M) on the zone after installing it.
-v
Verbose output from the install process.
