ArcSight Logger upgraded and no storage groups

Hello guys,

I upgraded my logger from 6.6 to 7.0, after login it says i need to configure storage groups for logger to be fully funtional(default and internal storage groups are no longer there). When i go into maintenance mode and try to create a storage group i get the error [There was a problem saving your changes: ERROR: column "archive_age" of relation "alg_storagegroup" does not exist]. I can view previous logs but new logs are not coming as there is no storage group i guess. Can someone help me solve this.

I also dont mind rolling back, if anybody can help me with the process, not so familiar with logger
