We are upgrading from Z9 processor to Z10 and Z/OS 1.9 to Z/OS 1.11. I would like to know will there be any impact (compatibility issues) on the existing code (all technologies CICS, COBOL, IMS, DB2), in general and particularly in Assembler code.
If there is any impact then please let me know or guide me to a place where i can find details on the impact.
I believe there should not be any impact. Just wanted to make sure my thinking is correct.
