Both Migrate and Protect come from the original PlateSpin PowerConvert. Novell split it in these two products after completing the acquisition of its subsidiary.
The idea behind this move is that customers may want to use the P2V migration engine for disaster recovery (something that PlateSpin evangelized for years) and so they want to have specific features for this task.
The new Protect 8.1 introduces the following features:
- Live incremental replication with block-based transfers
- File-level restore
- Support for live incremental replications in V2P migrations
- Support for VMware vSphere 4.0, Microsoft Windows Server 2008 and Windows Vista
