sp_dboption @dbname, 'allow wide dol rows', false
Before you downgrade Adaptive Server, verify that no wide DOL rows exist in any
table in these databases. Adaptive Server cannot find them, and thus does not warn
you about their existence. When you then downgrade to a version earlier than 15.7
ESD #2, Adaptive Server treats these as corrupt.
