Upgrading to version 9.4 by using the command line

You can use the command line interface to upgrade your version 9.3 IBM® MQ Appliance to version 9.4.

Before you begin

If you have a high availability (HA) configuration you must follow the procedure to update your HA queue managers, see Upgrading a version 9.3 HA configuration to version 9.4.
If you have an HA configuration with disaster recovery (DR), see Upgrading a version 9.3 HA configuration with DR to version 9.4.
If you have a DR configuration, see Upgrading a version 9.3 DR configuration to version 9.4. This topic gives guidance on upgrading one appliance at a time and so remaining operational.

You should back up your system before you upgrade, see Back up and restore.

Follow this procedure to upgrade your appliance to IBM MQ version 9.4.

Connect to the IBM MQ Appliance as described in Command line access.
Log in as a user in the administrators group.
Type mqcli to enter IBM MQ configuration mode.
Stop each of your queue managers:
```
endmqm queue_manager_name
```
Upgrade your appliance to the new firmware level:
```
boot image accept-license firmware_file
```
Where firmware_file is the file that contains the appliance firmware upgrade (see Overview of installing a new level of firmware by using the command line for details on obtaining the file). The appliance restarts.
Restart your queue managers:
```
strmqm queue_manager_name
```
Where queue_manager_name is the queue manager to restart.
