Conversion options

Two conversion tools can help you convert ISAM files to VSAM/KSDS files. You can use either IDCAMS REPRO or CCCA. The IDCAMS REPRO facility will perform the conversion unless the file has a hardware dependency. IDCAMS repro will only work for ISAM files on z/OS V1.6 or earlier. You must migrate ISAM to VSAM/KSDS before moving to z/OS V1.7 or later.

The COBOL conversion tool (CCCA) can automatically convert the file definition and I/O statements from your ISAM COBOL language to VSAM/KSDS COBOL language. The CCCA conversion tool is described in Conversion tools for source programs.
