Hi Yashwanth,
thank you for your reply.
Your assumption is right import was done via loader tool and as the source database is MaxDB7.6, we used the export tool for 7.6. Unfortunately the source database is not Unicode.
The exact version is DBMServer 7.6.03 Build 015-123-173-107.
We already migrated 4 databases from 7.6 (non Unicode) to 7.9 Unicode without problems.
Regards,
Werner
