Content Mirroring with WebDynpro ESS

Hi,

I created the ECC5 ESS package in my clients namespace. using Content Mirroring (this works nicely).

BUT the ESS role's Area/Group Area pages configed in the IMG still point to the standard installed ESS package. ie I nav to my ESS role click

Is there a tool simliar to Content Mirroring for the IMG to create all the necessary entries to match my new name space?

What is (current) best practice for webdynpro ESS? Can anyone point me to any docs? I've checked out the help but not seen anything to date...

Thanx
