About requirements for a new MSDP direct cloud tier storage server
You must use a new MSDP server with no existing disk pools as the new MSDP direct cloud tier storage server for the migration. You can reinstall and reuse the Cloud Catalyst server as the new MSDP direct cloud tier server. However, it may be better to use a new MSDP server with newer hardware and keep the existing Cloud Catalyst server intact. You can keep the existing Cloud Catalyst server as a failsafe in case of an unexpected failure during the migration process.
For more information about the minimum requirements for a new MSDP direct cloud tier storage server:
See About the media server deduplication (MSDP) node cloud tier.
Migration is possible to a system with less free disk space. However, an extra step is required after the creation of the new MSDP server and before you run the Cloud Catalyst migration. This extra step involves modifying the default values for CloudDataCacheSize and CloudMetaCacheSize in the contentrouter.cfg file.
For more information about CloudDataCacheSize, CloudMetaCacheSize, and the contentrouter.cfg file:
See About the configuration items in cloud.json, contentrouter.cfg, and spa.cfg.
You must be running the latest version of NetBackup (10.0 or later) that supports the migration feature on the new MSDP server. To do so, the primary server must also be running NetBackup 10.0 or later.
