[j-nsp] RSVP to LDP migration

[Giga Eth0]

Hi Experts,
 One of our customer has a extensive M-series based MPLS network which uses
RSVP and Admin-groups for TE. We are trying to simplfy the network and
introduce some other vendor nodes in the network and hence want to migrate
the network to LDP.

My preference would be to migrate the existing setup completely to LDP
before introducing any non-Juniper routers in the network.

Has anyone had any experience with migrating from RSVP to LDP?
If I enable LDP along with RSVP, my understanding is that LDP will form a
full mesh of seperate LSPs and not tunnel over RSVP. Is this correct?
Since LDP has a higher preference over RSVP, the LDP LSPs shall not be used
as long as the prefix is reachable by a RSVP LSP.
Disabling "protocol rsvp" shall fall over all traffic to LDP LSPs? Has
anyone had expereince with this in terms of traffic hit, outage time etc..

Any experiences or pointers related to this appreciated.

Regards
