I just tried to migrate my old KMail structure to KDE47 again last
night. The last attempt resulted in a complete disaster of lost messages
and parallel folder structures, and processes being run that completely
took over the machine and made using it almost impossible.
My methodology:
1) I logged out of KDE and restarted in Gnome
2) I renamed the .kde folder and copied the one from a non KDE47 machine
from work that was working perfectly, which happened to have the same
archive of mail as my home machine
3) I then logged out of Gnome and logged back in to KDE
4) There was an immediate message about migrating the address book that
appeared to succeed after a few moments - Kontact was not running at
this time
5) I started Kontact and got a message about the need to migrate my mail
and did I want to do that - when I answered affirmatively, I got an
almost instantaneous failure message
6) I then tried to run the kmail-migraror --interactive command - this
resulted in an error to the effect that this had already been run and
would not be run again
7) I then repeated steps 1-4 but, instead of then starting Kontact, I
ran the migrator first from a command line
8) This resulted in a lot of activity with a message log box indicating
that the process was running, and then, after a few moments, apparent
success
9) However, when I then opened Kontact, KMail was still a mess - this
time, I ended up with two "KMail folders" trees, with one having my old
folder structure from "Local folders" apparently migrated, but many
folders were not populated with messages, and a second "KMail folders"
tree with only my InBox and Sent Messages boxes which both had a lot of
messages in them
10) I noticed however that there was a lot of hard drive activity and
the messages count in the truncated "KMail folders" tree was changing,
going down, actually - so, I just let things run overnight
11) This morning, the hard drive activity has stopped, and KMail is
responsive, but, there are still two "KMail folders" trees, with a lot
of messages remaining still in the truncated tree; "Local folders" is
nowhere to be seen
12) The second "Kmail folders" tree, the one with all my migrated
sub-folders, now has a lot of messages in each of the folders
Unlike the last attempt, my computer is not bogged down, but top shows
several migration processes running - they look like this:
"8 root RT 0 0 0 0 S 0.0 0.0 0:00.00 migration/1"
there are a number of these running with different numbers after the slash
Also, resulting from the command line invocation of the kmail-migrator
command, I got tons of these:
"/usr/bin/kmail-migrator(31365)" Soprano:
"org.freedesktop.DBus.Error.UnknownObject - No such object path
'/org/soprano/Server'"
Conclusion: things are looking up, but, there are still significant problems
