When we try to upgrade UIM 20.4.0 using the upgrade wizard it returns the error " Fresh install is not supported, upgrade from 20.x is only supported"


  • Release: DX UIM 20.4, 23.4


Potential causes:

  • Previous versions of UIM were not correctly uninstalled
  • Permissions issue in confirming version information between the zerog.registry files and database.
  • The Nimsoft filesystem was copied to another machine but registry file from /var was not included


Confirm that the zerog registry has the correct information:

  1. Locate the .com.zerog.registry.xml file which can be found in the location displayed below:

    Windows-> C:\Program Files\Zero G Registry\.com.zerog.registry.xml   (note that this directory is normally hidden)

    Linux-> /var/.com.zerog.registry.xml


  2. Backup the file .com.zerog.registry.xml

  3. Edit the original file and match the section where it says product name="DX Unified Infrastructure Management" id="product id"....etc., with the information in


    from the DX UIM server filesystem.

  4. Save the change

  5. Attempt the upgrade again


Confirm that the installation is being run with the service account and that this account has database read/write permissions.
"Run as administrator" will not work if this account is unable to access the database.
