Hello,
We plan to move a 20+ years old Mainframe (CICS, Cobol and DB2) application to Windows platform with SQL.
The business request is to maintain uninterrupted operations while development is in progress and to incrementally release completed work into production.
There are tones of articles on the web and we identified “Rehostong”, “Regenrationg” and “Rewriting” as possible strategies: each of them have disadvantages and risks.
Would someone who went through Mainframe migration process share from their experience and make some suggestions on strategies to use?
If we were to choose the “Rewrite” options, during the development that will take years, we need to have data synchronised between Mainframe and SQL so the business can use the Mainframe and the new system.
Does anybody have any experience on how to achieve this?
Thank you,
Gabriela
