NethServer Version: v6.8 / v7 final
I have two Nethservers. One in the old and current stable version 6.8 and one on the new 7 final version.
I like to migrate all mails, only two inboxes, from one Nethserver to the other.
The following ways came to my mind:
1. Use the backup data function of Nethserver. But I am unsure what exactly is backuped and I don't know if it will work like I expect - only backup the mails (I don't use the fileserver).
2. Connect old and new inbox via any Mailclient and move the content from one Mailserver to the other.
I am curious if there is also a "copy-paste"-Way by just moving the Files from one Nethserver to the other, in case you have more than just two inboxes.
Is there a recommended way to do the migration in general?
