I have been using K9 mail for almost 15 years now. I have a number of “identities” (Settings>[Account name]>Sending Mail>Manage Identities) that I use for sending from multiple email addresses.
I recently added a second account within K9 because I’ve migrated to a new server. But I left the old account active because it’s got decades of email messages still on it and I want to maintain access to those messages.
Is there a way to migrate those identities to the new account?
