The OpenProject Enterprise on-premises edition extends the Community edition with additional Enterprise features.
To upgrade your existing OpenProject Community edition, sign in to your OpenProject instance with an administrator account.
If you already have an Enterprise on-premises token, click + Add enterprise token, paste the full token content into the dialog, and click Add to save.
If you do not yet have a token, you can either order an Enterprise on-premises token or request a trial token.
Once the token is saved successfully, your Enterprise on-premises edition is activated and the Enterprise add-ons become available immediately.
To upgrade to the Enterprise on-premises edition, click the Upgrade now button displayed on the Enterprise edition page. Alternatively, you can request a trial token to evaluate the Enterprise add-ons before purchasing.
After purchasing an Enterprise on-premises token or receiving a trial token, activate it by pasting the token into the Enterprise edition section as described above.
