Before changing to Mailman our list ran on majordomo. I still have those postings, in my IMAP mailbox, as a seperate directory.

My question is, how can I add those postings to the running list?

You first need to convert (concatenate) the messages into a Unix mbox format file. Then you can check the mbox with bin/cleanarch and add its contents to your archive with bin/arch.

Chronological overlap is minimal. Only for the final month there are postings on both sides. Even if I have to delete the ones from the old archive, that's not a problem.

You don't need to delete anything. If the same post was sent to both lists with the same message-id:, it will only appear once in the pipermail archive.

You may or may not wish to combine the majordomo mbox with the archives/private/listname.mbox/listname.mbox Mailman file to create a single archives/private/listname.mbox/listname.mbox file containing all messages, and then run bin/arch --wipe to rebuild the archive completely. This is not necessary, but if you simply add the old messages at this point, it will not be possible to rebuild the archive in the future without having message numbers reassigned, thus invalidating any saved archive URLs.
