RE: Guidance of Dynamics Portal Development, Test & Production Environments
Hi BiR,
Your subscription/tenant includes a single free instance of portal.
If you need to have portal enabled for all three environments, you will have to purchase additional portals for your other environments as well.
Although I would say that this is of course a necessity to have portals in all three environments, the one thing that you should be aware of is that portal data migration from one environment to another is not as straight forward as we would like.
There is a utiIity called Portal Record Mover from XrmToolbox, but I've heard some people having issues with and that it would not move all the records. The other option is the Configuration Migration tool to migrate the data from sandbox to production which seems to work pretty well, and gives you more control then Portal Record Mover.

Hope this helps.
