Oracle corp provides some migration assistance. In my experience, database migration is easier part ( in terms of man days, technical difficulties , testing etc.). Application conversion/migration could be tougher and more time consuming depending on the decision you have made ( complete rewrite/ convert on Oracle RDBMs). For Migration related help/service/toolkit, you can search oracle site or contact Oracle Folks (they have a migration expertise group within their org).
If you are using COBOL with embedded Sql ( Pro*CoBOL for Oracle product), then you will be able to convert to Oracle with less pain. It also depends on the architecture of the application or how the apps/rdbms inteface has been handled.
Other (significant)factor would be usage of special datatypes ( LOB/CLOB/Raw of your rdbms) and how that mapps to Oracle datatypes and Cobol/application data types

Thanks and Best Regards,
Pradip

hi list

Is there somebody on this wonderfull list considering to move away from the
mainframe computer with
his old RDMS to another platform (MS or UNIX) with oracle/sqlserver ? What are your scenarios : Big bang or keep 2 database in synch (how ?) Anyone with Unisys Clearpath systems with this case ?

Thanks for your contribution
