# How can I change a Process Configuration?

Changing the configuration of a Process is done in the Process Configuration Panel:

1. Start from the Instance Group Overview page, which is the first page right after logging in.
2. Click on the desired Instance Group.
3. Click in the desired Instance.
4. Click on the [ Instance Configuration ] button in the main menu.
5. Click on the Process you wish to configure.
6. Click on Configure Parameters... in the process edit panel.
7. Modify the Process as desired: Rename, Change Parameters, Add / Remove Parameters
8. Click on Apply in the top right corner if you are finished with this Process
9. You can undo/redo changes to multiple processes and/or instance configurations. You can also view any local changes using the [ Local Changes ] button.
10. Repeat the steps 5-8 with every Process that should be adopted.
11. Click on Save in the top right corner.

The changes are now saved but they are not yet active. The new version must now be Deployed and all Processes must be restarted so that the changes have an effect.

1. Saving Instance Configuration will automatically redirect you to the Instance Dashboard. You can also access the dashboard from the Instance Overview page by clicking an Instance.
2. If the current Instance Version is not the currently active one, a banner will show a hint and the required buttons to install and activate the current version.
   1. Access to older Instance Versions is provided from the [ Instance History ] button in the main menu.
3. Click on install and wait for the operation to complete.
4. Click on activate, this operation is typically very fast.
5. A hint (OUTDATED) will be displayed if a Process is running in an older version, for instance the version which was active until moments ago.
6. Stop the process you want to update by clicking on the Process. Click on the [ Stop ] button.
7. Start the processes by click on the [ Start ] button.
8. Repeat the steps 5-6 with each process that should be running from the new, now active version.
9. The hint (OUTDATED) disappears once all processes are running in the active version.
10. It can be desirable and OK to not restart certain processes, and leave them in the OUTDATED state. This highly depends on the software being deployed.

The configuration changes are now live and all Processes are running again. The Process Settings and the Process Control chapters provide more details about the step outlined in this tutorial.
