Need a study and comparison between upgrading/building out and securing an existing Active Directory (AD) environment vs. starting over with deploying a new AD solution. Want to know impacts and solutions centered around both scenarios. Existing AD has a very good chance of being flawed or compromised. Need to weigh in on all options because AD is already in production and need to consider impacts.
I need to deliver a feasibility study. Looking for research on the topic and also drawing from those with field experience.
