Backward Compatibility of Catalogic DPX Master Server and Clients

Catalogic DPX Master Server, device server, Open Storage Server (OSS) and all nodes operating as proxy servers for NDMP communication and for Virtualization functions must be on the same release version.

Catalogic DPX Master Server supports Catalogic DPX Clients with the same version and the past two versions, that is, DPX 4.8, DPX 4.6, and DPX 4.5. This backward compatibility is intended for migrating user’s Enterprises.

To assure the most reliable operation and enable the most efficient support, it is strongly recommended that clients be upgraded to the same version as the master server as soon as it is practical and that all components (servers and clients) are kept current to the latest patch level for their release version.

New features or enhancements to features in a new release will not be available for prior versions. New technical issues found with older client software may require upgrade to correct or continue troubleshooting.
