java stack and ABAP stack in upgrading SP

Hi,

I am on XI3.0 with SP 09 and upgrading SP to SP20 from SAP service market place.

How can I identify which is java stack and which is ABAP stack in evrery SP because Java stack can be directly upgraded to SP20 but ABAP stack has to be upgraded one by one (like sp 01..10..11..finally sp20).

Pls help

Thanks,

dushanth
