[Andreas Matthus]

Hallo,

my old data. It is verry hard!

Can I convert the data to the new format?

The error-messages are below.

Hi, could you please post the rest of the traceback as you have
snipped it in the place that was most important. Is there any
confidential data in the Data.fs ? If not maybe you could send it to
me so i could be sure that it evolves to new version properly.

Sorry I realized that My earlier reply probably went to the wrong list,
here it is again:

We included an export-import script, for the 0.8 -> 1.0 migration. So it
needs to be done by installing the 1.0 packages after the 0.8 packages.
Unfortunately this script only works from 0.8/0.9 to 1.0.

So I would suggest removing 1.2.4, re-installing 0.8 and then manually
installing 0.9, 1.0, 1.1 and finally 1.2.4. You can access repositories of
all these packages from http://snapshot.debian.net.

Unfortunately, as you've already installed 1.2, there may be some other
issues as well. So there may be some jiggery-pokery required.

But I strongly suggest that you make a backup of your configuration [1] file
and database [2] before trying this.

There were so many large structural changes in schoolbell as well as in
the way upgrades are performed between 0.8 and 1.2 that it was
impossible to maintain an upgrade path that skipped too many versions.
