The answer really depends on the features your current environment is using.

Some third-party applications (e.g. Oracle, Teradata, Siebel, PeopleSoft, etc) are "certified" to run on RHEL 5.x but not on 6.x so if you are using their official support it would be best to comply with their specifications in order to avoid a negative response when you *really* need vendor assistance.

You should also evaluate the current features your environment is using: Does it heavily rely on NFS and/or virtualization? These two are some of the topics that have changed the most in RHEL6 (compared to RHEL5) and might need some major adjustments during a migration.

IMO, it would be reasonable for a development environment or even UAT but I wouldn't mix different OS versions for prod environment unless it's extremely necessary or for a very short period of time (throughout the migration process, for example).

tcp-env

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME

       tcp-env - set up TCP-related environment variables

SYNOPSIS

       tcp-env [ -rR ] [ -ttimeout ] program [ arg ...  ]

DESCRIPTION

       The  input  for  tcp-env  must be a TCP connection.  tcp-env finds out information about that connection, puts the information into several
       environment variables as described in tcp-environ(5), and runs program with the given arguments.

       Usually tcp-env is run from inetd.  It might instead be run from another server that already sets up the right  environment  variables;  if
       PROTO  is  set  to  TCP  when  tcp-env  is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
       whether the input is a TCP connection.

OPTIONS

       -r     (Default.)  Attempt to obtain TCPREMOTEINFO from the remote host.

       -R     Do not attempt to obtain TCPREMOTEINFO from the remote host.

       -ttimeout
              Give up on the TCPREMOTEINFO connection attempt after timeout seconds.  Default: 30.
