Upgrading a Tezos Node
To update from sources:
Go to the Tezos directory git fetch git checkout v7.4 make build-deps eval $(opam env) make
- Stop the node before upgrading.
- If you’re a baker it’s a good idea to have at least two nodes to switch between. Smaller bakers can get away with upgrading between endorsements and blocks, but any baker with 30+ rolls may have a hard time maintaining 100% up-time running a single node.
- Check your node version after the upgrade. Run: ./tezos-node –help | tail -n 1
