[Evolution-hackers] mail migration

[Sasa Ostrouska <casaxa gmail com>]

Hi I know this is not direclty related to hacking on evolution, but I
would like to ask one advice.

I have about 5Gb of e-mails on my laptop which I use for work, and it
is still on evolution 2.26.3.
I would like to migrate now this stuff to evolution 3.6.x

What is the best way to do that ?

Simply upgrading evolution seems not to work, as it starts the wizard
as if .evolution dir doesnt exist.

Any tools around ?
