In compatible mode migration, you can keep all the application
code without any changes and recompile it with new JDK version that
BTT version 7.0 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 7.0 compatible lib.
- Recompile application code with new JDK version (JDK version 1.6).
- Perform function verification test and system verification test.
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.
