There are a few areas where DG COBOL is different from ANSI. Two major aspects are

File Handling - where LOCKED records are encountered (dependance on DG's proprietary file-handling)

SPACES in 9's fields are interpreted as ZERO (some programmers incorrectly believe that this even extends to 9's-COMP fields.) Hence data format in files and processes may need examination.

There are other areas, but it really depends on how complex the programs are - I've seen some code that is extremely hard to wind back to ANSI standard if the programmers were obsessed with using the DG extensions.

As for the destination platform - the OS on the destination platform should make no difference to COBOL.
