Issue/Introduction

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"

Environment

• Release: UIM 20.4, 20.4.5

Cause

• Previous versions of UIM were not correctly uninstalled

Resolution

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

   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
   
   <root_install_drive>\Nimsoft\_ca_uimserver_installation\.com.zerog.registry
   
   from the DX UIM server filesystem.
   
   
   
   

4. Save the change
