I am just wondering to know under which circumstances that custom built programs will fail to work after upgrade process. I would greatly appreciate if you can provide some documentation on it.
Thx in advance.

1) Obsolate Function modules - If your Z Program is using the FM which no more exists in New System the program will give syntax-error
2) SAP Cloned programs - If you have cloned SAP programs in Z program then you have to keep check if the standard delevered object is changed as part of Upgrade and them make the same changes in Cloned Objects
3) Unicode Compliant - If your system is not Unicode compliant you may require to do fixes to make it Compliant.
is some more helpful information.
Hope this helps!
