My team is running TeamCity under Enterprise Server License. We have recently decided to migrate the TeamCity server from one machine to another. Due to high volumn development activities we want to have the TeamCity completely verified working on the new machine, before turning off the old one. In other words, the old TeamCity machine will continue to run during the setup of new machine. If the setup on the new machine is not successful, we will continue to use the old server. This way we don't block our engineering team.
However we don't want to purchase another Enterprise Server License for $2000 just for this migration work. Is there any workaround that we can apply here to achieve the goal? E.g. can we just use the 60 evaulation license on the new machine, and once it is working, we turn off the old one and move the license to it?
