Hi Peter, I have just performed something similar. The information on the wiki is useful but there are lots of omissions in the document. For instance, there is no mention of how (or where) to install the 3.0 file structure. I tired many different methods but in the end I found the easiest was to do the following: - Bring up a new Koha system on the first release of Koha 3.000. - Dump the Koha 2.x database - Load the 2.2 database on the new 3.0 system - Preform the upgrade steps as listed here (http://wiki.koha-community.org/wiki/Upgrading_2.2 ) - Once the steps are taken you can then open the Webinf and run the database upgrade (if needed) - You can then continue up to the latest version of Koha Like I said, I just completed this and it went well. However, this will only take your data and if you have any customisations to your system you will need to migrate them another way.

We have an installation of Koha 2.2.5 at a remote site, and we wish to migrate the data to a new server running 3.4. Simply importing the MySQL dump file doesn't seem to do the trick - I get the borrowers but not the bibs etc. I've searched the archives, but most information about in-situ upgrades. Anyone point me in the right direction doco-wise? Peter Thompson Information Technology & Communications Unit Bendigo TAFE
