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

There will be a height coordinated upgrade on Flow mainnet on Monday, January 27th at 16:00 UTC.

Please be prepared to update your Flow Verification, Execution and Access node(s) at that time.

**Actions needed from your side on Jan 27th:**

- For the **Verification** , **Execution** and **Access** 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.

_Please complete this action within 24 hour of the announcement for the verification nodes_  
_If you are running multiple verification nodes, please restart the nodes one after the other (instead of all at once)._  
_Please complete this action immediately for the execution node_

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

Thank you for your cooperation,  
Flow Team.
