Migrating devices & template from one server to another

Hi There,

I am quite new to zenoss. Need your expert help. We have two zenoss servers. One running with some older version 1.1.2 and another with 2.1.

All the devices and templates are configured and working on older server. Now I want to migrate all these servers, templates, settings etc to new server.

Can you please guide me how can I do the same.

Thanks & Regards
