Key removal from staging site to live domain

Hi, we purchased your plugin and we used license on our staging site http://www.maalausteline.fi. We since have completed our work and move copy from that site to our actual store on domain: http://www.kiilakehys.fi.
Is it possible to remove key from maalausteline.fi so we can use it on our live site?
We are on process to move these licenses etc. to our actual site, so we can then safely delete this staging site.
Thanks!
