# Validating your migration to Amazon MQ
<a name="testing-and-validation"></a>

 Learn how to test and validate the availbability of your brokers using the following procedure. 

1. Subscribe to `Q1` on **AMQ\_APPLE** and `Q2` on **AMQ\_ORANGE**. Using a Network Bridge, create a queue replica on both sides.
**Note**  
 The process for external subscribers is the same as subscribing to local queues. 

    The following example shows the **AMQ\_ORANGE** broker with consumers in *us-east-1* and **AMQ\_APPLE** with consumers in *us-east-2* : ![ActiveMQ console showing queues table with two queues, each having one pending message.](http://docs.amazonaws.cn/en_us/amazon-mq/latest/migration-guide/images/ibm-testing-and-validation-fig-1.PNG) ![ActiveMQ console showing queues table with two queues, each having one consumer indicated by arrows.](http://docs.amazonaws.cn/en_us/amazon-mq/latest/migration-guide/images/ibm-testing-and-validation-fig-2.PNG) 

1. Both queues are now available to both brokers, producers can send messages to any broker, and subscribers can receive messages from any broker. For *JMS 1.1* compliant applications, change the endpoint URL to an ActiveMQ failover URL.
