Before performing a replication update, the replication service verifies that the target system is compatible with new data from the source.
If there are features in use on the source that are not compatible with the target and the features can be safely disabled, the replication service will disable the features, perform the update, and issue a warning.
If there are features in use on the source that are not compatible with the target and cannot be disabled, the replication service will not perform the update and issue an error.
NOTE: It is always best to upgrade the target as soon as possible.
Updates that break replication compatibility, are delivered as Deferred Updates. For the current list and description, see Updates in Oracle ZFS Storage Appliance Customer Service Manual and the Oracle ZFS Storage Appliance Release Notes for your current release.
