After MAR upgrade from 4.0 -> 7.0 login to ars_db fails with the message "inconsistent database structure". For me it is a bit weired to do the ars_db upgrade to 7.0 SP4 and then start the transport agent which is still in the 4.0 level but this is the way it is described in the upgrade guide in order to delete Blobs after MAR upgrade.
Is the guide here inconsistent? Don't we have to upgrade the tools and services first before deleting Blobs?
Did anyone experience similar issues?
