Reassemble all CICS® control tables using the CICS TS 3.1` macro
libraries, even if there are no changes to the macro externals. This applies
also to tables that you are reassembling only to migrate them to the CSD.
DFHCNV:
The requirement to reassemble your control
tables applies also to any DFHCNV data conversion tables that you use. This
is because CICS initialization fails when trying to load DFHCNV tables assembled
using macros from an earlier release.
