After an indescribable amount of pain and time wasted I was able to regain |
| 9 |
control over my mail. |
| 10 |
|
| 11 |
I recently migrated a kmail used nearly for ten years to the latest kmail2. |
| 12 |
Migration took around a month of struggle. |
| 13 |
|
| 14 |
It's mandatory to have nepomuk+akonadi running (I configured file indexing to |
| 15 |
run only on a folder containing a few files), it has to be checked for mail |
| 16 |
too. |
| 17 |
|
| 18 |
In the migration you'll lose your filters, your profiles, and the flag of the |
| 19 |
mail will be randomly changed (thousands of read mail will come up unread, |
| 20 |
"important" flag will be lost... And so on). |
| 21 |
|
| 22 |
If you try to reimport (after deleting the akonadi database as somewhere |
| 23 |
advised) the mail from ~/Mail you'll discover the the import tool is unable to |
| 24 |
handle maildir (or mailbox, I don't remember) format. If, like me, you used |
| 25 |
kmail for several years, then not all mail folders have the same format, given |
| 26 |
the fact that the default was changed during time. |
| 27 |
|
| 28 |
Beware also that full text indexing is on per default for every mail folder |
| 29 |
created. So, as soon as I imported a mail folder, I deselected this option by |
| 30 |
hand (under folder properties -> maintenance). |
| 31 |
|
| 32 |
So, this is the step-by-step guide to migrate to kmail2: |
| 33 |
|
| 34 |
* backup your ~ folder, especially ~/Mail, ~/.config and ~/.kde4 |
| 35 |
|
| 36 |
* make sure akonadi, nepomuk & co are running (with the command "akonadictl |
| 37 |
status" for example). |
| 38 |
|
| 39 |
* look carefully in ~/.xsession-errors if some errors appear related to |
| 40 |
akonadi, nepomuk, mysql, soprano, virtuoso... Do not migrate if you see any |
| 41 |
errors, fix them first. |
| 42 |
|
| 43 |
for example the following error is guaranteed to slowly and painfully drain |
| 44 |
all of your setup and mail to a black hole: |
| 45 |
|
| 46 |
Soprano: "Could not connect to server at /tmp/ksocket-sko/nepomuk-socket (No |
| 47 |
such file or directory)" |
| 48 |
|
| 49 |
* Delete everything no more necessary (mail messages, old accounts...). |
| 50 |
|
| 51 |
* Archive every folder you want to migrate and delete them from the old client |
| 52 |
|
| 53 |
* Take note of your filters, especially if some of them makes elaborate |
| 54 |
operations, mail account settings, profile preferences... |
| 55 |
|
| 56 |
* backup again, just to be sure |
| 57 |
|
| 58 |
* upgrade kmail, and start kmail2, let it run for the time needed (one night |
| 59 |
or more is normal) until the I/O and CPU load are back to a reasonable level |
| 60 |
|
| 61 |
* reimport archived folder (and disable for each one full text indexing before |
| 62 |
is started) |
| 63 |
|
| 64 |
* reconfigure filters, accounts, profiles... |
| 65 |
|
| 66 |
* backup for the last time |
| 67 |
|
| 68 |
Hoping to save someone else the waste of time I went through. |
