# Upgrading a Grid

Note that each Manager upgrade procedure does not make any modifications to the previous installation. If required, you can use this directory to roll back the upgrade.

## Primary Director Upgrade

| 1. | Shut down the Primary Director. The Engine Daemons move to the Secondary Director and the Engine Instances (which might be running tasks) continue without interruption.

| 2. | Upgrade the Primary Director.

| 3. | Start the Primary Director.

| 4. | Verify the the following Director and Broker mismatch controls are True: Admin > System Admin > Manager Configuration > Admin > Version Management >Allow Director Version Mismatch and Admin > System Admin > Manager Configuration > Admin > Version Management >Allow Broker Version Mismatch.

| 5. | Check that all the Brokers are logged in to it at Grid Components > Brokers > Broker Admin. The Engine Daemons move to the Primary Director. The Engine Instances do not restart.

## Secondary Director Upgrade

Follow the above procedure for the Primary Director. Shut down the Secondary Director and upgrade.

## Broker Upgrades

Failover Brokers must be upgraded after regular Brokers.

For each Broker:

Procedure

| 1. | Shut down the Broker. Within a few minutes Engines and Drivers migrate to a Failover Broker.

| 2. | Upgrade the Broker.

| 3. | Start the Broker. Verify that it logs in to the Directors.

| 4. | Verify that Admin > System Admin > Manager Configuration > Admin > Version Management > Allow Driver Version Mismatch is True.

| 5. | Within a few minutes Engines and Drivers migrate back.

## Upgrade the Engine Daemons

At this point, the Grid has been updated, but Engine Daemons are still at the previous version. Daemon upgrades result in Engine restarts, so do the following on each Broker when the time is appropriate:

- On each Broker, go to Admin > System Admin > Manager Configuration > Admin. Set Daemon Upgrade From Broker to true.

Note | The above step needs to be done as soon as possible.
