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 will not be able to 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.
