Are you installing Mailman 2.1.19 on the Red Hat system or using
whatever Red Hat rpm package that's available, and if the latter, what
is that? And, what Mailman will you be using on the RHEL 7 system?

I ask because the FAQ at <http://wiki.list.org/x/8486953> may be relevant.

Assuming you will be installing Mailman 2.1.19 from source, I would be
more concerned over potential difficulties due to the older Python than
with any gotchas from moving to a newer Python although there are some
compatibility issues with older Mailman versions and newer Python. See
<http://wiki.list.org/x/4030629> for more on both kinds.

My production server is Centos 5 with Python 2.4.3, but I also have
Python 2.7.9 installed and configure Mailman
--with-python=/usr/bin/python2.7. I wouldn't necessarily call it "good
practice", but it's certainly a viable approach.
