About migration from Cloud Catalyst to MSDP direct cloud tiering
NetBackup 8.3 and later releases include support for MSDP direct cloud tiering. This new technology is superior with improved performance, reliability, usability, and flexibility over the previous Cloud Catalyst product. You are encouraged to move to MSDP direct cloud tiering to take advantage of these improvements as well as future enhancements.
If you want to continue using Cloud Catalyst, you can do so on servers running NetBackup versions 8.1 through 8.3.0.2 because those versions are compatible with NetBackup 9.0 and later. Those older versions are supported as back-level servers for versions 9.0 and later NetBackup master server installations. After you upgrade the NetBackup master server to a version of 9.0 or later, you must use the command line to configure a Cloud Catalyst server. You cannot use the NetBackup Administration Console or the web UI with NetBackup 9.0 and later to configure Cloud Catalyst.
A nbcheck utility test has been added to the NetBackup install process to prevent Cloud Catalyst servers from being upgraded to version 9.0 and later. If Cloud Catalyst is detected on the server the install stops. The server remains unchanged, and continues to run the currently installed version of NetBackup after the upgrade is stopped.
