Upgrade from an earlier release

If you are upgrading from CICS® IA V3.1, V3.2, V5.1, or V5.2 it is best practice to take a copy of your ISPTABL data set before you run the ISPF dialog. The ISPF dialog automatically upgrades your ISPTABL data set by creating new members for the ISPF table format that is used by CICS IA V5.3.

If you are upgrading from CICS IA V3.1, the configurations can be stored only in a userid.ISPTABL data set. The old CIUCNTB table is upgraded and stored in the new, CIUCIC53 and CIUDB253, members in the ‘userid.ISPTABL’ data set. If you want to share this data set with colleagues you can copy it to a shared data set under a HLQ of your choice, and change the ISPTABL name as described in Modify your settings.

If you are upgrading from CICS IA V3.2 the configurations in the CIUCICST and CIUDB2T tables are upgraded and stored in the new, CIUCIC53 and CIUDB253, tables.

If you are upgrading from CICS IA V5.1 the configurations in the CIUCICT5 and CIUDB2T5 tables are upgraded and stored in the new, CIUCIC53 and CIUDB253, tables.

If you are upgrading from CICS IA V5.2 the configurations in the CIUCIC52, CIUDB252, and CIUUDB52 tables are upgraded and stored in the new, CIUCIC53, CIUDB253, and CIUUDB53 tables.
