Upgrading from Basic to Gold license

Hello Community,
I have an elk stack with 1 node each for Elasticsearch, Logstash, and Kibana with a basic license. I am thinking of upgrading from a basic license to gold. Are there any prerequisites or requirements that need to be satisfied before upgrading to gold? Please feel free to throw in my way documentation on the upgrade process.

Thanks for your answers.

No requirements, all you need is simply upload your new license from Kibana console.
