Simulation difference between r2007b and r2012b

Hello,
i recently received a new licence for r2012b and i am using simulink models that were developped and used with r2007b.
In particular i have a problem with a small function (which calculates a sliding average when activated and with an external sample number) that we developped using an 'Enable Subsystem' and 'SwitchCases' and Switchcase Action subsystems --> Even if the parameters and models are exactly the same, the outputs of r2007b and r2012b are definitely not the same.
My questions: - is there any known problem due to import in r2012b of r2007b models? - were there any changes in the definition of these blocks and their parameters?
Thanks!
Matthieu

Matthieu: It might help if you explain how they're different. Is the different of the order of 1e-5 for instance, or significantly different?

I have worked on a couple of occasions with the similar symptoms. It is very diffcult to resolve without having the model, whoch is why I recommend contacting Technical Support. This is what root causes I have found in different cases:
- Difference was caused by different computer architectures (32/64 bit) and there a good numerical reasons why this can happen
- Difference was caused by different c compilers in cases where e.g Simulink Accelerator was used
- Difference was caused by different processor manufacturers and their respective BLAS library
- Difference was caused by a change of a default option of a MATLAB command that was called
