Re: [Evolution] Migrating from Thunderbird via import without duplicates

[christopher <topherbuckley gmail com>]

Then what exactly is the use case for importing from Thunderbird as per 
[the 
manual](https://help.gnome.org/users/evolution/stable/import-apps-mozilla.html.en)? 


As I have between 50 - 100 GB of mail to sync, with it all backed up 
locally, I'm happy to try to break things in an effort to avoid days if 
not weeks of re-syncing. Are there details on this process (warnings 
heeded) anywhere?

I have access to both the mail server and local machine for all but my 
gmail accounts. I'll test the process on less important demo accounts as 
well.

I guess I could copy my local backups to the evolution maildir, ssh into 
my mail server and rsync the maildirs. I'd hope it'd recognize there to 
be no need to resync and duplicate everything at that point, but maybe 
others have tried this with failure?

I have no idea how I'd approach this for the gmail accounts though as I 
can't rsync or ssh into the gmail server. Any hints in the right 
direction and I'm happy to tinker and break things! Thats why I have 
backups! :)

Best regards,
Christopher
