I'm going to be doing a new Mailman installation on a Red Hat Enterprise Linux (RHEL) system 5.11 with Python 2.4.3. The goal is to convert existing ListProc mailing lists to Mailman without having to change the addresses for the lists. I've done a similar conversion in the past many years ago and expect it to take a few months to get all my list owners moved to the to the new MLM.
When all the lists are eventually converted or retired, I will then migrate this new Mailman installation from the above platform to a new RHEL 7 installation with Python 2.7.
My question is, are there any quirks or gotchas that I should be aware of in going from the old RHEL/Python platform to the new one? Is there anything I can do on the old system now that will make migration to the new platform easier? For example, I could use Pythonbrew to install a private v2.7 Python on the old box for Mailman to use, rather than relying on the system's older Python.
FWIW, we're still on RHEL 5 and have been using the Python 2.7 RPMs from iuscommunityproject for several years. Here's the repo file:
