we face this problem today.
I change the preanalysismigrationversionnumber of database mendixsystem$version to 4.0.0.
It workes.You can try.
one possible reason is using a higher version of mendix to connect to this database.
Hi Giridharan,
Actually you are trying to downgrade from Mendix versions higher to lower. Otherwise if you want to downgrade to older version , restore the database backup to older version.
Thanks
