6.4.1 Tasks required after an upgrade installation (when upgrading from version 10 to 12)

This section describes the tasks that you must perform after upgrading the version of JP1/AO from 10 to 12 in Windows.

When you have just upgraded the version, back up the environment. If you upgrade the version of JP1/AO from 10 to 12, you will no longer be able to restore the data that was used in version 10. If a problem occurs during operation, restore the data that you backed up immediately after the upgrade installation.
When the upgrade installation finishes, the port number is reset to the default port number. If you do not want to use the default port number, manually set the desired port number.
In a cluster environment, after upgrade installation finishes, make sure that the same port number is set in the following definition files. Note that the setting locations differ depending on the communication protocol used for communication between JP1/AO and the Web browser.

For HTTP protocol:
- The user_httpsd.conf file in Common-Component-installation-folder\uCPSB\httpsd\conf
```
Listen port-number
Listen [::]:port-number
```
- The command property file (command_user.properties) in shared-folder-name\jp1ao\conf
For HTTPS protocol:
- The user_httpsd.conf file in Common-Component-installation-folder\uCPSB\httpsd\conf
```
Listen 127.0.0.1:port-number
```
- The command property file (command_user.properties) in shared-folder-name\jp1ao\conf
In JP1/AO version 12, because the names of installation folders and Common Component commands have been changed, review their settings.
