Image Optimizer on Dev and Live sites

We just purchased the following add-on: Image Optimizer for XF 2.0

We want to install it and test it on our dev site first.

Is is possible to install the plugin on our dev site and then again on our live site once we complete testing?

Thanks,
Barry

Has no one ever moved from a dev site to a live site?

How does one raise a ticket with the developer?

Thanks,
Barry

I did ask the developer about the addon linked above (5 days ago), but he gave no answer.

You can install it in local before make it live on prod.
