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?

wiki::toolkit::testlib
Wiki::Toolkit::TestLib(3pm) User Contributed Perl Documentation Wiki::Toolkit::TestLib(3pm)
NAME
Wiki::Toolkit::TestLib - Utilities for writing Wiki::Toolkit tests.
DESCRIPTION
When 'perl Makefile.PL' is run on a Wiki::Toolkit distribution, information will be gathered about test databases etc that can be used for
running tests. Wiki::Toolkit::TestLib gives convenient access to this information.
SYNOPSIS
use strict;
use Wiki::Toolkit::TestLib;
use Test::More;
my $iterator = Wiki::Toolkit::TestLib->new_wiki_maker;
plan tests => ( $iterator->number * 6 );
while ( my $wiki = $iterator->new_wiki ) {
# put some test data in
# run six tests
}
Each time you call "->next" on your iterator, you will get a fresh blank wiki object. The iterator will iterate over all configured search
and storage backends.
METHODS
new_wiki_maker
my $iterator = Wiki::Toolkit::TestLib->new_wiki_maker;
number
use Test::More;
my $iterator = Wiki::Toolkit::TestLib->new_wiki_maker;
plan tests => ( $iterator->number * 6 );
Returns the number of new wikis that your iterator will be able to give you.
new_wiki
my $wiki = $iterator->new_wiki;
Returns a fresh blank wiki object, or false if you've used up all the configured search and storage backends.
configured_databases
my @configured_databases = $iterator->configured_databases;
Returns the @configured_databases array detailing configured test databases.
Useful for very low-level testing only.

CAVEATS
If you have the Search::InvertedIndex backend configured (see Wiki::Toolkit::Search::SII) then your tests will raise warnings like
(in cleanup) Search::InvertedIndex::DB::Mysql::lock() -
testdb is not open. Can't lock.
at /usr/local/share/perl/5.6.1/Search/InvertedIndex.pm line 1348
or
(in cleanup) Can't call method "sync" on an undefined value
at /usr/local/share/perl/5.6.1/Tie/DB_File/SplitHash.pm line 331
during global destruction.
in unexpected places. I don't know whether this is a bug in me or in Search::InvertedIndex.
