  An APM Command Center Server (ACC) upgrade with upgradetool.sh/bat fails with this error message. (The version information may vary according to your environment.):

[ERROR] Upgrade failed: Version of the tool from the package provided is lower than the current one ( < Downgrades are not supported.


 Version comparison is implemented as lexicographical instead of numerical comparison. Therefore “ <” is assumed and the installation aborts.



APM 10.5.2.


  Override the version to upgrade from by using -Dcom.ca.apm.acc.upgrade.version=

This helps by overriding the old version string used for checking.

The steps to do this are below:

1. Open upgradetool.sh/bat with an editor

2. Add a line “-Dcom.ca.apm.acc.upgrade.version= \” to the $JAVA_CMD string at the end of the file.

3. Save the file.


4. Verify that the whole command should now read:



-DTAR_PATH="`which tar`" \



-Dcom.ca.apm.acc.upgrade.version= \

-jar /tmp/acc-upgradetool.jar $*

Additional Information

This issue will be fixed in a future version or service pack of CA APM.
