[Mailman-Users] Moving lists with large archives to new server

I am required by my host to change server hardware as the current hardware is out of support and needs replacing.

I will be going from 32-Bit Debian Wheezy to 64-Bit Jessy when it is released, and will probably upgrade to Mailman 2.1.19 from 2.1.18-1 using my own custom made packages.

All the configs for the system will be pushed via Puppet including ~/Mailman/mm_cfg.py, and ~/lists and ~/data can be copied over very quickly.

My question revolves around the list archives.  If I start Mailman up before they are copied across, it is likely there will be waiting messages and these will get archived to a new mbox file.  I want to reduce downtime in moving the lists, but the mbox files are around 25GB, and there are a couple of lists which take the majority of that.  I was going to index the messages once the mbox files are copied over, but what is the smartest way to get these moved without downing Mailman for too long?
