Moving from V5 to V6 is very straightforward. Moving to V6 from V4 or earlier is very similar to the move to V5.
The need to use PDSEs, a COBOL V5+ produces Program Objects, which cannot be stored in a PDS.
Bad data, and the way V4 and earlier worked with bad data.
Bad programs, and the way V4 and earlier worked with bad programs.
There are some new compiler options to consider, some are intended as migration aid (to spot bad data). There's RULES. Some new language constructs (EXIT PERFORM, EXIT PARAGRAPH, EXIT SECTION, for instance, but don't use them).
