Hi, I found there is a portal_migration tool in my Plone site and I tried to use it to upgrade from 1.0.1 to 1.0.5. The result is below: (I checked "Dry run" but I don't know what it's mean...) Starting the migration from version: 1.0.1 Attempting to upgrade from: 1.0.1 Upgrade to: 1.0.2, completed Attempting to upgrade from: 1.0.2 Upgrade to: 1.0.3, completed Attempting to upgrade from: 1.0.3 Upgrade to: 1.0.4, completed Attempting to upgrade from: 1.0.4 Upgrade to: 1.0.5, completed Attempting to upgrade from: 1.0.5 No upgrade path found from that version, migration stopping End of upgrade path, migration has finished Dry run selected, transaction aborted Something is missing in my install... What can I do? Thanks.
