Hey, folks. I've searched the list archive but haven't found a relevant thread 
yet. Any pointers would be helpful.

I have a handful of lists in a 2.1 instance for which I have web archives but 
not original .mbox files. Is there a way to migrate those lists, including the 
years of archives, to 3?


Ideally you would have Mailman's archives/private/LISTNAME.mbox/LISTNAME.mbox files which is all you need. If tho don't have those, but you have the periodic archives/private/LISTNAME/*.txt files, you could concatenate those for a list into one mbox file. In some cases the From: headers will be munged. I.e., they may be like

From: user at example.com (user name)

and you would at least want to replace ` at ` with `@`.

If you don't have even those, you would have to somehow process the HTML files into messages for a mbox. There is no way to import the HTML directly into HyperKitty.
