Have anyone tried SQL Server database subsetting provided by this tool :

http://swissql.com/products/datamigr...migration.html

They claim that, the tool does the below :

"Criteria based data migration (data subsetting) is supported when migrating from Microsoft SQL Server(i.e SQL Server is the source database). User can set the filter criteria for a table based on which the rows(matching the criteria) will be migrated. If criteria is set for a table, then its dependant tables will also be migrated based on its relationship"

Please let me know if anyother data subsetting tools available, so that I can compare the quality of migration before we actually proceed with the migration.
