Can I generate a six months trial license of an add-on?

[Kalas Richard]

I'm using trial license on my test server. But it expired every month. 

So could you please let me know how to generate a license for 6 months ?

Thanks,

Richard

If you have a commercial license for your production server, you can get a developer license to use in your test server.
