Snapvault transfers using ndmpd.preferred_interface on the primary storage system fail
Protection Manager fails to expire hourly snapshots on the backup node
DataFabric Manager may take more time to update the SnapMirror relationship details and SQL service may cause high CPU utilization.
Data transfer reports stopped updating for relationships originating from Open Systems SnapVault and DFMMonitor logs are spammed with error messages
Snapmirror monitoring very slow due to reading of snapmirror logs
CVE-2011-3192 Apache Range Header DoS in DFM and OnCommand
Ensure you have a DFM Db backup before upgrading then you can proceed directly either to 5.0.2 or 5.1 from 4.x.
If you were hitting bug 439756, the background post-upgrade processing could take some time to complete as the 5.X code will automatically run the workaround after a successful upgrade as well as on a regular basis afterwards.
OC UM Core 5.1 will split your DFM server into either 7mode or clustered mode, so if you have a mixed environment be aware that you will have to make that decision during the upgrade.
