How to update RabbitMQ / Erlang

1. Open CMD as Administrator and run the command “cd C:\Program Files\TEOS Manage\RabbitMQ\RabbitMQ\rabbitmq_server-3.13.1\sbin”
   
   Note that the path can be different based on the location of TEOS and the RabbitMQ version installed. Adjust the command based on its true path.
    
2. Now run the commands “rabbitmqctl export_definitions definitions_backup.json”. This will create a backup of the RabbitMQ data.
   
    
3. We now need to install the new versions of Erlang and RabbitMQ. 
   Erlang version 28 is currently not compatible with RabbitMQ, version 27.3.4.2 is. see: compatibility matrix for the more information.
    
4. Erlang installer: Erlang installer
   Select the “Download Windows Installer” button. 
   
   RabbitMQ installer:RabbitMQ installer 
   Navigate down and search for "Downloads on GitHub" and choose the “Windows installer”
    
5. Before installation the RabbitMQ service needs to be stopped, open “Services” and stop the service called RabbitMQ.
   
    
6. Now the old Erlang version needs to be uninstalled, open “apps and features” and uninstall Erlang.
   
    
7. The new Erlang version can now be installed. Make sure a compatible version is selected. Run the downloaded Erlang installer and make sure that the destination folder is "C:\Program Files\TEOS Manage\Erlang".
    
8. RabbitMQ can now be updated, this will be an in-place update so make sure not manually remove it. Run the installer and select yes when it prompts to remove the old version.
    
9. After installation the installer will prompt to start RabbitMQ, select yes.
    
10. Erlang and RabbitMQ have now been updated to a later version.
