Normally if we are making upgrades to mission critical applications in 100s of servers in a large organization with a risk management team we should notify them if if we plan any upgrades which may cause an outage.
You should test in a test bed, make a plan, identify the risks and notify your risk management team.
Upgrading the core "mission critical" application on 200-300 web servers requires planning and team work.
What happens if you make a mistake and bring down the application(s)? Do you want your organization to be caught off guard when customers are calling in, angry their service is down?
You have described a major infrastructure upgrade. You certainly do not want to upgrade with YUM over a manually installed configuration until you have completed tested this idea in a test bed, insure you have backups of each application and database before hand, etc. In other words, you need a plan in coordination with your IT risk management team, customer service, etc.
This is how we work as IT professionals.

Hi Folks,
Just a quick question here, about Legacy Zones. Well more about how to determine if you are actually in one, on logging into a legacy zone - is there a quick way of checking that?

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attach if outdated packages/patches are found on the target system.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.
