My team has an instance of teamcity professional which we have been running for around 12 months.We have recently purchased a license for teamcity enterprise as we have outgrown the capacity of the professional license. The information provided to use from Jetbrains was a serial key and links to download pages. We obviously wish to transition our existing instance, its configuration and data when we being using the enterprise license. What is the best way to upgrade from professional to enterprise? I have searched the document but found nothing on this topic. Is there somewhere I can enter the serial keys provided to unlock the extra functionality provided by enterprise? Or do I need to backup and re-install the enterprise version?
