You wonder if it is possible to convert a License Key from Perpetual to Subscription without losing your current License Key. 

1. Here's how it works:

Yes, you can upgrade your Perpetual License Key to a Subscription License Key. You have lifetime rights for your Perpetual License Key and if you decide to upgrade it both License Keys will continue working under the following rules in section 2 or 3.

For more information on how the License System works, visit the article below:

• Knowledge Base:  How does the license system work?

2. What happens if you upgrade a Perpetual License Key to a Subscription License Key?

2.1: The status of your current Perpetual License Key is set to 'Upgraded' in your Lumion Account.

2.2: A new Subscription License Key is issued and the Lumion Account is updated.

2.3: The new Subscription License Key retains the same number of Seats as the upgraded Perpetual License Key.

2.4: This means that if (for example) your Perpetual License Key has 2 Seats and you upgrade it to a Subscription License Key, an equal amount of 2 Seats can still be used in parallel on different machines.

2.5: Your Perpetual License Key can still be used if already installed on one or more machines.

3. What happens to your Perpetual License Key if you cancel your Subscription?

3.1: Your Subscription License Key will be set to 'Disabled'. This means it can no longer be used after the Subscription Term ends. When the grace period expires, status will be changed to 'Expired'. See section 3.2 below:

• Knowledge Base: 3. Subscription renewals and changes

3.2: Your Perpetual License Key is then reactivated and set to 'Active' and you will only be able to use the Lumion version(s) associated with the Perpetual License Key.

In case you decide to renew your Subscription License Key during the grace period, then section 1. is applicable again.

3.3: Important! Lumion files are not backwards compatible.  If you saved your Lumion files in a newer version of Lumion, and you revert to a previous version of Lumion that was associated with your Perpetual License Key, then you will not be able to open the .LS files.
