Some CICS programs written in assembler language may have to be reworked.
These applications are more prone to violate the CICS API restrictions.
These applications are more prone to violate the CICS API restrictions.
Also, be sure to review all EXEC CICS commands for changes in VALUES.
The name of the CSECT within module DFHECI changed from DFHECI to DFHELII.
So, be sure that your LINKEDIT included DFHECI.

An application program that passes the address of a COMMAREA to another
application program can be above 16MB, below 16MB, or it can be a zero
address. A COMMAREA can be in CICS-key storage or USER-key storage (if
CICS is running with storage protection), or in read-only storage (possibly
obtained using an MVS GETMAIN call). The length of the COMMAREA can be a
positive value or zero, but a negative value always results in an error. Therefore,
the user must provide a condition check for a negative value in the user
programs.

If you have any Distributed Transaction Processing (DTP) applications that use
CICS APPC commands, changes to the CICS implementation of the APPC
architecture could mean you need to change the APPC applications before you
can migrate them to CICS TS.

The DFHMSCAN utility program, which is available with CICS/VSE is
recommended for reviewing CICS application program libraries. This program
can be run against VSE application libraries to find out which application
