Changing license on SQL when using an AlwaysOn Cluster

Hi SQL experts,

Maybe a simple one, but I'm looking for someone who has actually done this to make sure it's safe.

Need to setup 2012 or 2014 SQL enterprise and an alwayson availability cluster, but haven't got the license yet.... Was considering using either a trial or a dev (msdn) license until we get the proper license (it will be in development for at least a month before being in a production environment so using MSDN should be legit)

Question is, if I upgrade or apply the proper license when I get it, does it pose any issue to the instance or availability cluster? Is there any danger of having to amend/recreate the cluster or anything like that?

You can't upgrade from a Trial to an Enterprise Edition. For Development Edition you should not have any issue.

Thanks Vitor,

So there should be no issue upgrading from MSDN license to enterprise license without an affect on existing services/instances.

Yes, that's correct. Just run the setup.exe and chose the Edition Upgrade option. SQL Server will be unavailable during the process but then should be all ok after the setup.
