This assumes you are familiar with the basic usage of the Gateway Migration Utility.

Let's say you want to create a Cluster Wide Property using the Gateway Migration Utility. First, create an XML file.

touch createCWP.xml

Add the following to the XML file. In this example, the Cluster Wide Property will have a key of "foo" and a value of "bar".

<l7:ClusterProperty xmlns:l7="http://ns.l7tech.com/2010/04/gateway-management"> 
  <l7:Name>foo</l7:Name>
  <l7:Value>bar</l7:Value>
</l7:ClusterProperty>

Issue the following command to create the Cluster Wide Property.

/path/to/GatewayMigrationUtility.sh restman
-host apig.example.com
-port 8443
-username john.doe
-password f5VPX0yUJPg.m4BrjdgMv84UgktddJD3xA
-method POST
-path '1.0/clusterProperties'
-request createCWP.xml

Or the -argFile option can be used, to reduce the number of options that are used on the command line.

/path/to/GatewayMigrationUtility.sh restman
-argFile example.properties
-method POST
-path '1.0/clusterProperties'
-request createCWP.xml

You can then use the Gateway Migration Utility to ensure the Cluster Wide Property was created.

/path/to/GatewayMigrationUtility.sh restman
-argFile example.properties
-method GET
-path '1.0/clusterProperties'
-query 'name=foo'

Which should return something like this.

<l7:List>
  <l7:Item>
    <l7:Name>foo</l7:Name>
    <l7:Id>1a5b56dfad45645645fd5464df65</l7:Id>
    <l7:Type>CLUSTER_PROPERTY</l7:Type>
    <l7:TimeStamp>2019-03-29T00:55:11.088-05:00</l7:TimeStamp>
    <l7:Link rel="self" uri="https://example.com:8443/restman/1.0/clusterProperties/1a5b56dfad45645645fd5464df65"/>
    <l7:Resource>
      <l7:ClusterProperty id="1a5b56dfad45645645fd5464df65" version="1">
        <l7:Name>foo</l7:Name>
        <l7:Value>bar</l7:Value>
      </l7:ClusterProperty>
    </l7:Resource>
  </l7:Item>
</l7:List>
