The LMF function was removed from ISPF in z/OS® V1R2.0. Users of LMF are encouraged to migrate their existing LMF-controlled libraries to SCLM. There are several differences between LMF and SCLM, but the basic library manager function is similar, so migrating the hierarchy from LMF to SCLM is straightforward. SCLM has a full set of services, so most dialogs that use LMF services can be converted easily to SCLM. SCLM also includes a complete set of Configuration Management options.
