If you are upgrading from a version older than ESB 5.0.0, you should first upgrade to ESB 5.0.0 and then upgrade to WSO2 EI 6.1.0.


From WSO2 ESB 5.0.0 onwards, it does not support processing any mediators added after the send mediator in a given sequence because it may lead to erroneous behaviors when the message stream is consumed by the send mediator in passthrough scenarios. Therefore, if you have sequences with mediators after the send mediator, you need to change those sequences to have the send mediator inside a clone mediator, thereby, it will clone the message and process it separately. For example, see below.

Code Block
<clone sequential="true">
                   <endpoint key="ABC"/>
             <switch xmlns:ns="http://org.apache.synapse/xsd" source="get-property('XYZ')">
                  <case regex="CASE1 ">
                       <log level="custom">
                           <property name="#### CASE ####" value="IN CASE1"/>
                       <sequence key="TEST.PQR "/>
                        <log level="custom">
                           <property name="#### DEFAULT ####" value="IN DEFAULT"/>
