# Migrating to BSR from Auto-RP

Migrating to BSR from auto-RP requires that you upgrade all PIM routers in the domain to support BSR. However, until all routers are BSR-capable, continue to use auto-RP.

After all routers are BSR-capable, switch from auto-RP to BSR as follows:

1. Use the no ip pim send-rp-discovery scope command to stop PIM in the network by disabling all auto-RP mapping agents. This results in flooding to an empty map.
2. Reconfigure auto-RP mapping agents as candidate BSRs by using the ip pim bsr-candidate command.
3. Reconfigure auto-RP candidate RPs as BSR candidate RPs by issuing the no ip pim send-rp-announce command and then issuing the ip pim rp-candidate command.
