Hi there,

We are planning to upgrade latest FLARE patch level in our two Clariion CX4-120 boxes.

These two boxes in Mirrorview/A replication and currently running with same FLARE patch level.

Please clarify me on the below queries,

Our upgrade plan is DC first and after a week we will upgrade DR site. is this ok?

Is it ok to run DC with latest code and DR with current code until DR upgrade?

Hope Flare upgrade is NDU, During upgrade is there any impact in Mirrorview/A replication?

How do we check compatibility with latest FLARE code and all other dependencies like HBA driver, HBA firmware, SAN switch FOS, Host agent? do we have any portal/matrix for compatibility check like NetApp's IMT portal?

Thanks in advance.

Regards,

Dhakshinamoorthy Balasubramanian
