Hi gang,
I want to migrate mm21 to mm3, by changing the domain of the list, thus LIST@OLD_dom to LIST@NEW_DOM. I run on debian, with the debian testing version of mm3 installed.
Is there an obvious way to do that? Right now I think
- create new list
- read mm21 pickle to change the domains in it, write to temporary pickle
- run mailman import with that pickle
- read the archive mailbox and change the domain in all the headers
- change the domainname in bodies and attachments (?)
- run hyperkitty import
This may be the project of a madman... any advice?
When you say 'read blah and change the domain', are you doing that programmatically or beforehand? I'd do it beforehand. And whichever way you do it, it will work.
In its simplest - computational power not taken into account:
sed -i.BAK 's/OLD_dom/NEW_dom/g' pickle archive_mailbox
- run the indexing.
