After performing an ONTAP upgrade, how should you verify that replication relationships remain intact?

• A. Ignore replication status as it is unaffected.
• B. Only check the source cluster's health.
• C. Verify replication relationships, monitor status, and check consistency across sites.
• D. Reinitialize all replication after upgrade.

Answer: (C)

After an ONTAP upgrade, you should confirm that every SnapMirror relationship is still defined, healthy, and delivering current data across sites. The best approach is to verify the replication relationships on both clusters, monitor their live status and any lag or errors, and perform cross-site data checks to ensure the destination reflects a recent point-in-time copy of the source. This includes checking last transfer times, lag, and any reported issues, and running integrity checks if available to confirm there is no data divergence. A comprehensive review ensures protection remains intact and helps catch any upgrade-induced problems that a single-cluster or passive check might miss. Reinitializing replication or ignoring status isn’t advisable unless you’ve identified a real divergence or a broken relationship requiring remediation.
