If you missed the Heimdall v2 upgrade, you’ll need to update your node to the latest Heimdall version to resume syncing. First, back up your data, then follow the official Heimdall v2 migration guide to upgrade properly. Restart your node after the upgrade. Running v1.2.0 won’t sync due to protocol changes. Check the Polygon docs or community channels for any additional migration steps or patches.
