I have an A2 VM currently configured to be 'standard' virtual machine tier. Can I switch that over to the 'basic' tier while it is live? There is no auto-scaling or load-balancing. It's a 'stand-alone' machine running a simple website and database.
Will it go offline? Will data be lost? Will I need to rebuild / re-provision it?
... or, as I hope, will it just update the billing information.
