migrate older e-mails to local mailbox

[Tamas Papp]

Hi,

Gmail is bugging me about my mailbox getting full. I thought I would
migrate older (eg pre-2020) emails to a local mailbox (of course backed
up), and have mu index that too.

What would be the best way to do this (the migration, not the indexing;
I know how to do the latter ;-)). Is there a script I can use?

From the very mu4e, I move those emails to a new mailbox folder (created on the
fly if needed, if I recall correctly) that is not synced.

You can test it with just one message, copying it first.

Thanks, but I was hoping for a more automated solution (talking about
30k messages). Eg search for all messages before a given date in
mailbox, move them to a given folder.

Yes, that's what I'm suggesting. You search them, you mark them, you
move them.

I only wrote about a simple test before you move those 30k messages.
