After you use the migration tools to migrate to WebSphere Application Server Version 6.1, you should verify the results of the automatic Cloudscape database migration and manually migrate any Cloudscape database instances that are not automatically migrated by the tools.
See Overview of migration, coexistence, and interoperability and Premigration considerations.
WebSphere Application Server Version 6.1 requires Cloudscape Version 10.1.
Cloudscape Version 10.1 is a pure Java database server that combines the Apache Derby runtime with the opportunity to use the full services of IBM Software Support. For comprehensive information about Cloudscape Version 10.1, see the Cloudscape section of ibm.com at http://www.ibm.com/software/data/cloudscape/.
