I'm assuming you have CICS program with BMS which has IMS DB calls.
New MFS maps should be created for the BMS screen
PSB shoud be changed
New Transactions should be defined in IMS DC
Create new program with similar logic of existing CICS program, with IMS DC calls. And you need to do the scheduling which might be in current CICS IMS DB programs.
You need to add all the required components in the program like Working storage IO areas, linkage, DLI calls.
Instead of COMMAREAS you might have to use SPA.
This list of changes is not complete, it really depends on how complex your CICS IMS DB program.
I would suggest first read IMS DC manual and get understanding of how IMS Dc works.
