The installation script first checks to see if the upgrade path is supported by comparing the INTERFACE value in /usr/tank/server/VERSION with the version being installed. If the difference between these values is greater than 1, the new package will not be able to communicate with other metadata servers in the cluster. This is important during a non-disruptive upgrade. You can create the file /usr/tank/server/.IGNORE_VERS to force the upgrade.
Before upgrading to this level, an intermediate upgrade is required. Contact your service representative to determine the supported upgrade path.
