[Evolution] Migrating from 2.32.2 to 3.0.2

[Ed Avis <eda waniasset com>]

Hi, I'm trying to upgrade Evolution from 2.32.2 (shipped with Fedora
14, after applying updates) to 3.0.2 (Fedora 15).  I have one machine
running the old version and one running the new.  I tried to copy the
files from the old system to the new system, then start Evolution and
have it migrate things automatically.

The directories I copied were

    ~/.evolution
    ~/.local/share/evolution

(Most stuff was in the latter; ~/.evolution was almost empty.  I think
that 2.32.2 has already done the migration into ~/.local.)

When I then start 3.0.2 it tells me it needs to migrate from mbox to
maildirs and that 'an mbox account will be created' with the old
stuff.  However, when the Evolution window appears the inbox is empty
and I don't see any of my saved folders.  Apart from a single message
in the outbox, the account is empty.

Is there something special I need to do to make the upgrade work?  Or
did I not copy over the correct files?

Below is the stuff that evolution 3.0.2 prints to the console, when I
start it for the first time and ask it to migrate the data.

% evolution
Gtk-Message: Failed to load module "pk-gtk-module"

  mv /home/susan/.evolution/mail/local/folders.db
/home/susan/.local/share/evolution/mail/local/folders.db
  rmdir /home/susan/.evolution/mail/local
  rmdir /home/susan/.evolution/mail
  rmdir /home/susan/.evolution/tasks
  FAILED: Directory not empty (contents follows)
          tasks

I think I see what might be the problem: there was a folders.db file
in both the old place (~/.evolution) and the new
(~/.local/share/evolution).  For running 2.32.2 this is not a problem
- I think it ignores the old location.  But when the migration happens
it overwrites the good folders.db with the empty one from
~/.evolution.

I'll try copying across ~/.local/share/evolution only, leaving out the
~/.evolution directory, and see if the migration works.
