Just to add more information about your question. Holders of commercial and academic licenses can create a free developer license for use in a cold standby, development or testing server.
The license is perpetual, with access to software updates for the same maintenance period as the commercial/academic license.
The technical contact for the license can generate a developer key by logging in to http://my.atlassian.com
I hope this helps. Please let us know if you have any questions.
Thanks for your replies i got my answer actually i have $10 Starter Licensesand documentation says
$10 Starter Licenses do not include access to Developer Licenses. Starter License holders can use our evaluation license to test upgrades or purchase a second Starter License.
