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

We will perform a height coordinated upgrade on Flow mainnet on July 10th at 8:30 AM Pacific. Please be prepared to update your Flow node at that time.

**Actions needed from your side on July 10th:**

- 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.

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.
