Reset the data
In case something goes wrong and your node can't be recovered, you can reset it and sync it again.
Reset the data:
rm $HOME/.desmos/config/addrbook.json $HOME/.desmos/config/genesis.json
Your node is now in a pristine state while keeping the original
config.toml. If you had any sentry nodes or full nodes setup before, your node will still try to connect to them, but may fail if they haven't also been upgraded.
Make sure that every node has a unique
priv_validator.json. Do not copy the
priv_validator.json from an old node to multiple new nodes. Running two nodes with the same
priv_validator.json will cause you to double sign.
After the reset, you can sync back your node with state-sync, check how depending you are doing this on:
