Replacing a PE/P MPLS Router

We've had one of our P/PE devices die last night and im looking for tips on how to swap it out with as least disruption as possible.

The issue is that we take full routing table from our Tier1 provider and when we put a new device in, it blackholes traffic for about 30 minutes while routes are being imported from RIB to FIB. We also advertise our /21 and /22.

​

This router has 1 internet uplink, 3 connections back to other PE's and P devices.

​

I was thinking as follows:

1. Shut down the uplinks to other PE's
2. Power up. Remove the export policy for its internet neighbor. Let it take the full table from our Tier1. Wait 30 minutes
3. Bring up its uplinks to other P/E's

Is there anything else ive missed out? or is there a better/less disruptive way to do it?
