Hi, i am preparing the Data Migration Plan for migration of existing data from ADABAS to DB2. The data volume can be as huge as 200 GB. Since it is impossible to verify all the data migrated, does anyone know of any industry practices for the percentage of data to be verified for different record range.

For example,
small sys: 0 to 1million records (1%)
medium sys: 1 to 10million records (5%)
large sys: 10million records and above (10%)

Thanks Much!
