We just upgraded OPS/MVS from R13.5 to R14.0. Several functions are not working
Option 4.2 - MSF Links. I cannot connect my R14.0 to my R13.5 MSF links
Option 5.2 - Unable to see the version number
Release : 14.0
OPSMAIN was using STEPLIB so it was getting the 14.0 modules, however, the LNKLST had not been refreshed so modules from release 13.5 were being taken by other tasks.
Refreshing LLA solved this problem.
Make sure that no modules from previous releases are being used in STEPLIBs, LNKLST, or LPA
