You can move a catalog to another volume, even to a volume of a different device type, by using the EXPORT and IMPORT commands or by using DFSMSdss.

When you use IMPORT CONNECT for a tape volume catalog, you need to specify VOLCATALOG.

You can also move the catalog to another system by connecting it to the system and disconnecting it from the original system

If you connect a catalog to a sharing system, ensure that the share options for the catalog are (3 4); this is the default for the DEFINE USERCATALOG command. If the share options are (3 3), first use the ALTER command to change the share options to (3 4). The device on which the catalog resides must be defined as shared for each system.
