For example, you should not be in the process of creating a virtual disk. Configuration changes should not be made within 48 hours before beginning the upgrade. Proactive event notification can be used to alert you if a critical event occurs during the 48 hours before the upgrade. NOTE: • The leveling process does not impact the upgrade. If leveling is in progress, the upgrade can be performed. The leveling will be suspended during the upgrade and resumed when the upgrade is complete. • Ensure you suspend any processes or applications that may change the storage system configuration, such as backups and snapshot creation or deletion.

•
Perform the controller software upgrade using the local management server (the server running
HP Command View EVA that is local to the EVA being upgraded).
•
Before you upgrade the controller software, you must upgrade HP Command View EVA (and
layered applications) to the required version on both the source and destination storage
systems.
•
Before you upgrade any storage system in an HP Continuous Access EVA relationship, ensure
