Migration considerations

If you are migrating from an earlier version of ZDT/IMS, you cannot use the HFM1POPT module that was created for the earlier version. If you do, you may get unpredictable results.

However, you can use the source code from which the earlier version of the HFM1POPT module was created. Add any new parameters that you need to specify, then assemble the source using the latest version of the Z Data Tools macro library (HFM.SHFMMAC1) and lastly link-edit the module.
