No docs on validator server migration

We need to replace our Validator server with new hardware running the latest RHEL version. The new hardware is up and running and I'm ready to install Rippled and then make it a Validator. I want to use the same domain name, and I don't want downtime of our Validator presence. What's the best way to go about the replacement? Thanks.

Start running the new rippled instance without validation enabled, so you can make sure it's stable.

You can generate a new validation token with your existing domain name. Alternately, you can just copy the validation token from your old config to your new, once the new machine is running well.

Make sure to update any peer reservations that need your IP address to whitelist by communicating your new address, if you have one.

There will be a small amount of downtime from when you switch off your old machine to when you start validating on the new machine. Make sure the old validator is off before running the new machine as a validator, to avoid the network getting confused by two different machines identifying as the same validator (this is less of an issue if you generate a new validation token with a higher sequence number).

Also ensue that you don't run two machines with the same node seed in the config or the same wallet.db file. You might want to copy wallet.db along with rippled.cfg and validators.txt to the new machine, as wallet.db stored amendment voted and identity credentials.
