Good Morning SCCM Ghost,

First off this doesn't make any sense, if you have 100 Primary sites and 400 secondary sites, for multiple reasons.

The whole environment needs  to be re-build from the ground up. Since this is the case there is zero point in moving forward with CM07 as it end of life is just around the comer, you need to move to CM12 maybe even to CM16.

Since you need to move to CM12 / CM16 you need to analyze your environment, this will result in a huge saving of servers and therefore reduce the cost to manage the environment.
