From Community to Enterprise — Odoo13 Dev Document（https://www.odooai.cn） 13.0 documentation

Depending on your current installation, there are multiple ways to upgrade your community version. In any case the basic guidelines are:

Backup your community database
Shutdown your server
Install the web_enterprise module
Restart your server
Enter your Odoo Enterprise Subscription code

On Linux, using an installer

Backup your community database
Stop the odoo service
```
$ sudo service odoo stop
```
Install the enterprise .deb (it should install over the community package)
```
$ sudo dpkg -i <path_to_enterprise_deb>
```

Update your database to the enterprise packages using

$ python3 /usr/bin/odoo-bin -d <database_name> -i web_enterprise --stop-after-init

You should be able to connect to your Odoo Enterprise instance using your usual mean of identification. You can then link your database with your Odoo Enterprise Subscription by entering the code you received by e-mail in the form input

On Linux, using the source code

There are many ways to launch your server when using sources, and you probably have your own favourite. You may need to adapt sections to your usual workflow.

Shutdown your server
Backup your community database
Update the --addons-path parameter of your launch command (see Source Install)
Install the web_enterprise module by using
```
$ -d <database_name> -i web_enterprise --stop-after-init
```
Depending on the size of your database, this may take some time.
Restart your server with the updated addons path of point 3. You should be able to connect to your instance. You can then link your database with your Odoo Enterprise Subscription by entering the code you received by e-mail in the form input

On Windows

Backup your community database
Uninstall Odoo Community (using the Uninstall executable in the installation folder) - PostgreSQL will remain installed
Launch the Odoo Enterprise Installer and follow the steps normally. When choosing the installation path, you can set the folder of the Community installation (this folder still contains the PostgreSQL installation). Uncheck Start Odoo at the end of the installation
Using a command window, update your Odoo Database using this command (from the Odoo installation path, in the server subfolder)
```
$ odoo.exe -d <database_name> -i web_enterprise --stop-after-init
```
No need to manually launch the server, the service is running. You should be able to connect to your Odoo Enterprise instance using your usual mean of identification. You can then link your database with your Odoo Enterprise Subscription by entering the code you received by e-mail in the form input
