Changing namespace uri after custom model has been deployed

[leonardo_celati]

Is it possible to change namespace URI after model has been deployed, and being used on a few nodes ? Currently there are some aspects in it.
I am talking about changing this:

<namespaces>
   <namespace uri="http://www.mywebsite.com/model/custom/1.0" prefix="my"/>
</namespaces>
‍‍‍‍‍

to this:

<namespaces>
   <namespace uri="http://www.newaddress.com/model/custom/1.0" prefix="my"/>
</namespaces>

No.    You are defining a new namespace.  

You may (or may not) get an error about the "my" prefix being duplicated.

Your "few deployed nodes" will continue to use the "http://www.mywebsite.com/model/custom/1.0" namespace.
