How to create a patch and patch my custom bundles in the Fabric containers?

My application is OSGi based and runs in Fuse Fabric. The version of Fuse is 6.2.1.
I have 4 physical nodes. On each node runs a Fuse Fabric Container that hosts the OSGi bundles of the application.

I want to know how to patch correctly specific OSGi bundle of my application.
For example: When I do a small change in my DAO layer, I want to apply a kind of patch to Fabric so that all 4 containers have the new version of the DAO bundle.

In the Fabric documentation for Fuse 6.2.1 is shown how to apply a patch (zip file), but doesn't tell how to create the patch zip file.

My questions are:
1. How to create a patch with my new version bundles?
2. Is the method described in the Fabric guide applicable for my situation? 19.7. Patching a Fabric Container with an Incremental Patch
