How to midy Supported Client List using XML Access

There are 3 steps to changing the supported client list using XML Access (xmlaccess) utility:
1. Take export of the entire portal using the following command and input file:  

Command  
xmlaccess -in Export.xml -user userid -password password -url portal.example.com:10039/wps/config -out Result_File.xml  

Export File

<?xml version="1.0" encoding="UTF-8"?>
<request
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="PortalConfig_1.4.xsd"
    type="export"
    export-users="false">
    <portal action="export"/>
</request>

2. Create Update_SupportedClients.xml file as follows:  

Import File
 

<?xml version="1.0" encoding="UTF-8"?>
<request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="PortalConfig_1.4.xsd" type="update">
    <portal action="locate">
        <client action="update" domain="rel" markup="html" name="Default HTML Client" objectid="M_0000000000000000000000C010" ordinal="75">
            <useragent-pattern>.*</useragent-pattern>
        </client>
        <client action="update" domain="rel" markup="xdime" name="Default XDIME Client" objectid="M_VBL70VO20G0000I1D5CPPM3043" ordinal="50" uniquename="mwp.default.xdime.client">
            <useragent-pattern>.*</useragent-pattern>
        </client>
    </portal>
</request>

Change the values of the "objectid" from the file (Result_File.xml) exported in the step 1 above. Change the "ordinal" and any other value as per your requirements.

3. Import the changes into Portal using following command:

Command
xmlaccess -in Update_SupportedClients.xml -user userid -password password -url portal.example.com:10039/wps/config -out Result_File.xml 

If everything went well then you will see success message at the end.
