We are refreshing our R3 Dev environment to be a copy of our final R3 UAT environment. This is so that we can go back to review any testing or setups. There are also few items that need to be done manually and won't go live until Dec 1.
One of our RTM environments is being upgraded with R3 components, this is the beginning steps of the upgrade. When we shut down production which is only HOURS away, we'll copy the production database to this environment and perform the steps to split off the business data.
So in just about 15 hours our Production environment will be going down! And the split will take place.
