[Serusers] Third party Registrations in SER proxies

As a follow up question . Do we have a mechanism by which a SER proxy can
get/pull information from another SER proxy about clients registered. Here
is a scenario.

I have deployed a SER proxy - "PROXY-A" to which a very large number of
users are registered. I need to bring down PROXY-A for maintenance and
replace it with PROXY-B but donot want the users to register again. Is there
some way by which PROXY-B can pull the info out of PROXY-A so that the
customers donot see this transition.

Is it possible for a SER Proxy to fwd all the learnt registration
information to a backend central registrar. If any call needs to be routed
(eg: an invite message being received) the proxy can lookup the central
registrar and route the call .

thanks,
sandeep
