Hi Rishika,
Thanks for getting in touch! I’m happy to help you here with licensing.
You can move your license from one site to another by logging into our site and heading to My Account > License Keys. The step-by-step instructions are here:

You mentioned wanting to run the license on both sites. It’s worth noting you have a Personal license, which allows licensing on a single site. That said, the plugin can be installed on both sites with no functional impact to either one. In other words, the plugin will work on both sites, regardless of whether the license is active or not because the license only activates automatic updates.
At the same time, there are a couple of other ways in which you can use a single license on both a live and development site, which is outlined in more depth here:

Does this help clarify things a bit? Please let me know. 🙂
Cheers!
Geoff
