Thanks K. I gave some wrong information. Our customer uses ez version 3.4.2, and I see here: http://ez.no/download/ez_publish/changelogs/ez_publish_3_5/upgrading:
"If you are upgrading from a version prior to eZ publish 3.4.4 you must follow the upgrade path version by version until version 3.4.4 is reached".
I here got a problem. I don't find the upgrade from 3.4.2 and up to 3.4.3 and to 3.4.4 :(
Hope someone can point me to the correct upgradefiles here..so I can get this site into a better and newer shape.
I just migrated from 3.3-3 to 3.6.1 and I did it by downloading 3.3-4, 3.3-5, 3.4-0, 3.4-1 up to 3.6-1 and than unpack each distribution over the existing installation after serious backups. You can find the releases here:
