Upgrade Process

After the proposal status is marked as passed, the upgrade plan will become active. You can query the upgrade plan details using the following command:

cheqd-noded query upgrade plan --chain-id cheqd-mainnet-1

This will return output similar to:

height: "1000"
info: ""
name: <name of proposal>

At block height 1000, the BeginBlocker will be triggered. At this point, the node will be out of consensus, awaiting the upgrade to the new version.

The log messages like these should be expected:

5:17PM ERR UPGRADE "<proposed upgrade name>" NEEDED at height: 1000:
5:17PM ERR UPGRADE "<proposed upgrade name>" NEEDED at height: 1000:
panic: UPGRADE "<proposed upgrade name>" NEEDED at height: 1000:

Once the new application version is installed and running and 1/3 of the voting power on the network is restored, the node will resume normal operations.

Automatic upgrades with Cosmovisor

If your node is configured to use Cosmovisor, the upgrade action will be performed automatically at the specified block height.

To check if your node is configured to run with Cosmovisor, run the following command:

systemctl status cheqd-cosmovisor.service

If there's a running systemd service, running this sub-process /usr/bin/cosmovisor run start, then your node is using Cosmovisor.

Additionally, you should make sure that in your cheqd-cosmovisor systemd service configuration file, you have these environment variables set to true:

Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"
Environment="DAEMON_RESTART_AFTER_UPGRADE=true"

By default, the configuration file can be found at this location - /usr/lib/systemd/system/cheqd-cosmovisor.service;.

Manual Upgrades for Standalone Nodes

For standalone nodes, follow the instructions in our installation guide. Make sure to choose the release suggested in the software upgrade proposal.

Node Built from Source Code

If you are running a node built from source, you will need to:

1. Refer to the upgrade proposal details.

2. Check out the git tag corresponding to the latest release. This is important in cases code in our main branch doesn't match the latest release.

3. Build the updated binary.

Docker Users

Additionally, we're also publishing the docker images in our GitHub Container Registry, so in case you're running cheqd node in Docker, you can always find the latest image there.
