The expiration date handling is dependent upon whether the data set is VSAM or non-VSAM and whether the source data set is cataloged or not cataloged:

• VSAM data set: The catalog expiration date is the same as that of the source data set. In the VTOC, the expiration date is set to 99365. For an indexed VSAM data set, the expiration date in the VTOC for the index component will also be 99365.
• Non-VSAM data set: The catalog expiration date of the source data set is used for the catalog expiration date of the target data set. The expiration date in the VTOC of the source data set is used for the VTOC expiration date of the target data set.
