+#### Upgrading from older versions
+
+Due to XML schema changes to correct an inaccurate domain name 2 files will need to
+be updated:
+
+ 1. `etc/bootstrap.xml`
+ 2. `etc/management.xml`
+
+In both files change the XML namespace from `activemq.org` to `activemq.apache.org`,
+e.g. in `bootsrap.xml` use:q:
+```xml
+<broker xmlns="http://activemq.apache.org/schema">
+```
+And in `management.xml` use:
+```xml
+<management-context xmlns="http://activemq.apache.org/schema">
+```
