Hello Flow **Access** , **Verification** and **Execution** Node Operators,

There will be a height coordinated upgrade on Flow mainnet tomorrow **Feb 13th at 16:00 UTC**.

Please be prepared to update your Flow nodes tomorrow.

**Actions needed from your side at that time:**

* * *

1. **Verification** node operators -

Please update your docker to the new tag that will be provided that day as part of an announcement and restart the node.

Do **not** delete the data folder.

_Please complete this action within 24 hour of the announcement_

_If you are running multiple nodes, please restart the nodes one after the other (instead of all at once)._

* * *

1. **Access** node operators -

Please update your docker to the new tag that will be provided that day as part of an announcement and restart the node.

Do **not** delete the data folder.

* * *

1. **Execution** node operators -

Execution nodes will stop executing blocks at a particular height and must be restarted with a new docker tag.  
You can monitor the block height by querying the metric execution\_runtime\_last\_executed\_block\_height.  
e.g. `curl -s http://127.0.0.1:8080/metrics | grep -E '^(execution_runtime_last_executed_block_height)'`

Once the execution node has stopped executing blocks, the height reported by the metric will no longer advance.  
One that happens, do the following:

1. Stop the node
2. Update the docker tag to the one provided that day.
3. Start the node.

Do **not** delete the data folder.  
_Please complete this action immediately for the execution node_

* * *

_No action needed for Collection, Consensus and EVM Gateway nodes._

This is **NOT** a spork, and the network will keep running during the upgrade.

Thank you for your cooperation,  
Flow Team.
