This guide will show you how to safely upgrade a Lotus node to a newer version.

Installing an update

Usually, if you are updating Lotus, it as simple as rebuilding and re-installing the software after pulling the latest state for the chosen branch and repository. You can do that with:

git pull
git checkout <branch or tag>

Once the new version is checked-out, rebuild and re-install as explained in the installation guide.

You can verify your current version with:

lotus --version # for the lotus binary
lotus version   # for the currently running daemon
