Upgrading from OX 6.22.11 Rev7 to current version

[Garry]

I have a customer system running 6.22.11 Rev7 on SLES 11. As the system is ancient, and can not be updated (we tried ...), I've started installing a new system with the current version of Open Xchange.
Installing the new system isn't much of a problem (I hope), but I am concerned as far as the database goes ... Once I have the new system up and running, can I just (as I did on previous re-installs) stop OX, import the oxdatabase_6 dump into the new install, restart OX and it will migrate the database to the current schema? All I can find at the moment are update instructions for in-place updates ...

Help appreciated!

After having the new system mostly operational, I tried to migrate the database ... seems like it's failing ...

Is this due to the attempt of updating the DB schema from the "ancient" version to the current? How can I fix this?

[Garry]

Funny ... during the first attempt, I had OX stopped before doing the import. I tried once more, without stopping OX first, and this time it seemed as if the data (at least calendar - still need to have the customer check other infos) was working. Anyway, on a stop/start of the OX server, I got the same error again ...

OK, seems like I got it to work ...
After trying some of the stuff from here: http://oxpedia.org/wiki/index.php?title=UpdateTasks unsuccessfully, I then replaced the contents of the old DB dump's "updateTask" table with that of the current version's dump ... after then re-running all the updateTasks, I can now log in to OX again, and the data from the dump seems to be present ... still need to do more tests and have the customer to a quick check, but at least I got rid of the error...
