## Upgrade will take place December 14, 2021

The upgrade will take place at a block height of `8695000`. At current block times (around 7s/block), this block height corresponds approximately to `Tuesday, 14-Dec-21 6:00:00 UTC`. This date/time is approximate as blocks are not generated at a constant interval.
The upgrade will take place at a block height of `8695000`. At the time of writing, and at current block times (around 7s/block), this block height corresponds approximately to `Tuesday, 14-Dec-21 14:49:50 UTC`. This date/time is approximate as blocks are not generated at a constant interval. You can stay up-to-date using this [live countdown](https://chain-monitor.cros-nest.com/d/Upgrades/upgrades?var-chain_id=cosmoshub-4&orgId=1&refresh=1m) page.

## Chain-id will remain the same

The chain-id of the network will remain the same, `cosmoshub-4`. This is because an in-place migration of state will take place, i.e., this upgrade does not export any state.

## Preparing for the upgrade

### System requirement
32GB RAM is recommended to ensure a smooth upgrade.

If you have less than 32GB RAM, you might try creating a swapfile to swap an idle program onto the hard disk to free up memory. This can
allow your machine to run the binary than it could run in RAM alone.

```shell
sudo fallocate -l 16G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
```

### Backups

Prior to the upgrade, validators are encouraged to take a full data snapshot. Snapshotting depends heavily on infrastructure, but generally this can be done by backing up the `.gaia` directory.
