You have a set of datasets accessed via Fileshare server server1. They are in c:\fsdir\datasets, where c:\fsdir is the Fileshare directory for server1. Those associated with your payroll application all have names beginning payroll, and you move these to c:\fs2dir\data, where c:\fs2dir is the Fileshare directory for server2. In future you want to access these files via server2. To update the catalog:
set mfsyscat=c:\catalog\catalog.dat set mfalloc_loc=$$server1\datasets mvspcrn "$$server1\datasets\payroll" "$$server2\data\payroll"
