How to migrate data from one active objects default namespace to another

I am trying to add the new ao module with another namespace. I am losing the tables with the default namespace.

Is there a way I can use the new namespace and migrate the data from existing tables to new tables.

I appreciate all your opinions and suggestions. I have added below configuration.

<ao key="ao-module">
       <description>The module configuring the Active Objects service used by this plug-in</description>
       <entity>com.test.repo.MyConfigEntity</entity>
   </ao>

  <ao key="ao-module" namespace="com.test.mytestplugin">
     <description>The module configuring the Active Objects service used by this plug-in</description>
     <entity>com.test.repo.MessageEntity</entity>
  </ao>

Thanks,
Kiran. M

ao module key (ao-module) must be unique

Thanks. I tried that way, still I am not able to get the data from the earlier table which has default namespace.
