"It is recommended that you cancel this upgrade. Your system has failed the compatibility check. The enforce server version (11.5.0.05030) is not compatible with this upgrade"
The upgrade log from the Enforce server shows:

SEVERE: Compatibility check failure: The Enforce server version (11.5.0.05030) is not compatible with this upgrade
This issue occurred because the wrong upgrade jar file was used and since the upgrade jar was not newer than the existing version the compatibility check failed.
The file downloaded and used in this instance was called Symantec_DLP_11.5_MP1_Upgrader_Lin-IN.zip
The upgrade was successfully completed after downloading and upgrading with the jar file contained in Symantec_DLP_11.5.1_ReleaseUpdate_Lin-IN.zip
