From time to time we at Mediachase come across customers who decide to purchase their deployment license within 24 hours or less of the time they wish to actually go live.  We strongly suggest that you do not wait until the last day or even last couple of day(s) to purchase your deployment license.

This is due to the fact that you may encounter unforeseen issues/errors when or after you migrate to your production server.   These errors are usually with configuration and set up and may cause you to miss your deadline if not fixed in a timely manner.  

Don't put yourself in a situation that may cause you to miss or postpone your deadline, please give yourself ample time to QA/test your solution in your production environment.  Mediachase can provide you with a Q/A-Production Deployment License free of charge so that you can test.
