+## Migration from version 1 to version 2
+
+If you update from sg_job version 1, you need to execute the Upgrade Wizard, that migrates the old area field.
+To do so, please visit the Install Tool and click on Upgrade Wizards. Check the Job Upgrade Wizard and execute it.
+This Wizard will migrate your area data into department records.
+
+Also please be aware of changes to the Fluid template regarding the area -> department migration and change the area
+occurences of variables in the template to department records accordingly.
+
+This version also introduces correct exclude field configurations for the tables, so check your backend user 
+and backend usergroup permissions and adjust them accordingly.
