In compatible mode migration, you can keep all the application code without
any changes and recompile it with new JDK version that BTT version 6.1.x supports.
If you want to have your applications run on the new BTT version while having
the minimum application code changes, you can adopt the compatible mode migration.
The following diagram shows the compatible mode migration:
The migration process for mixed mode migration is as follows:
- Replace old BTT lib with BTT version 6.1.x compatible lib
- Recompile application code with new JDK version (JDK version 1.5)
- Perform FVT and SVT
The advantages of the mixed mode migration are:
- Less migration cost
- Fewer BTT skills needed
The disadvantages of the mixed mode migration are:
- Not keeping pace with BTT product strategy and IBM® front office strategy
- Not leveraging BTT new features in the new version
- No improvement on performance, scalability, stability and reliability
