Dear all,

just struggling a bit while getting the existing datas of an app back to an upgraded version of the same where we've added three tables. I tried to clone the previous version and do an upgrade on it - hoping that the existing data can be used fruther. Unfortunately a strange error says that the sceurity CSV cannot be processed because the ids of the new models we've included are not known by odoo.

Is there anything we can do in order to take over the existing data of the previous version of our app to the upgraded one or do we have to export all models/tables step by step from the old version to Excel and import it into the uprgraded version? Wouldn't be that nice...

Any help on this is greatly appreciated - many thanks in advance for your advice and tipps

Carl
