Hello Flow **Execution** and **Verification** Node Operator,

We will perform a height coordinated upgrade on Flow mainnet on June 7th at 8:00 AM Pacific. Please be prepared to update your Flow node at that time.

**Actions needed from your side on June 7th:**

- For the **Verification** node, 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.

- For the **Execution** node, please run the admin command that will be provided, and then once a specified height has been reached, the node will stop. At this point, update the docker to the new tag and start the node. Do **not** delete the data folder.

_Please complete this action within one hour of the announcement._  
_If you are running multiple verification nodes, please restart the nodes one after the other (instead of all at once)._

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

Thank you for your cooperation,  
Flow Team.
