When performing a rolling upgrade, update the target servers first. After the
upgrade is complete, the sources will automatically reconnect to the targets.
Upgrade the sources when convenient.
l
If you are using a chained configuration, update the last target first, then update the
middle server acting as both a source and target, and update the production source
last.
l
If you are using a configuration where the source is an older version than the
target, you will not be able to restore from the newer version target back to the
older version source. You must upgrade the source to the same version as the
target before restoring.
l
Use the following procedure to upgrade Storage Mirroring Recover on a cluster. If
both your source and target are clusters, use the following procedure on the target
cluster first, then on the source.
1. Move all cluster resources to one node.
2. Upgrade to the new version of Storage Mirroring Recover on all of the other
nodes.
3. Move the cluster resources to one of the upgraded nodes.
4. Upgrade to the new version of Storage Mirroring Recover on the last node.
5. If needed, move the cluster resources to the desired nodes.

If you are upgrading GeoCluster and are currently using the GeoCluster Replicated
Disk as the quorum resource, you will need to select quorum resource before
upgrading. See
Configuring your cluster for GeoCluster installation for more
information.

If you have protected clusters with an earlier version of the Application Manager,
you should disable protection before upgrading to this version of Storage Mirroring
Recover.
