Remote Replication is compatible between most Oracle ZFS Storage Appliance software versions. Compatibility failures are caused if a replication update uses a feature that is not supported on the replication target. Features are delivered with software updates or as deferred updates.
For details about compatibility and deferred update features for each software version, see the Oracle ZFS Storage Appliance Remote Replication Compatibility document (Doc ID 1958039.1) on My Oracle Support (http://support.oracle.com/).
If you are using the BUI, go to Maintenance > System. If you are using the CLI, navigate to maintenance system updates and enter show.
For example, if the source share uses large blocks, ensure that the replication target provides support for this feature.
For more information, see Deferred Updates in Oracle ZFS Storage Appliance Customer Service Manual.
Set the values according to your site's security requirements. The versions and at least one of the ciphers must be identical on the source and target appliances. Oracle ZFS Storage Appliance systems running older firmware might not support ciphers offered in newer TLS versions.
