The installation script first verifies that the upgrade path is supported by comparing the INTERFACE value in /usr/tank/admin/VERSION with the version being installed. If the difference between these values is greater than 1, the new package cannot communicate with the metadata server. 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.
