[Mailman-Users] Adding Mhonarc to existing Mailman installation

I am building a new Mailman 2.1.9 installation tree, and want to configure it with Mhonarc and Mnogosearch. I notice that the Mhonarc patches change the config.pck version number from 96 to 96.2 because there seem to be some changes to the file definition.

I have signed up on the mmi mailman-mnogosearch mail list and see what's involved, but have mailman-specific questions.

What happens if I move a config.pck running on stock 2.1.9 (version 96) to this new tree? Is there something in Mailman that figures out how to remunge the config.pck file?
