There will be many occasions where an opeartor has to deal with moving the active validator to another node. sdo makes it simple by providing a single command to do that.

 sdo validator switch-hosts-ssh

It will ask for the network and public key of the validator.

? What is the validator network? (Use arrow keys)
❯ testnet
  mainnet
✔ What is the validator network? testnet

Once chosen the network, sdo will ask for pubkey of active validator

? What is the public key of active validator?
✔ What is the public key of active validator? 32nTAQSAxzSbvURguFvfz5FX1g4enbvgyttMYHr1KJqM

Next provide the public key of hot backup validator node. This key should be the one defined when you created the backup validator.

? What is the public key of hot backup validator?
✔ What is the public key of hot backup validator? sdobhP2sSx2d3nb4UMMg6bnKeeWXgSMkGLzFxeSC6tG

Rest will be taken care of by sdo. It will also update the inventory file to reflect changes in the nodes.
