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.
