GOAL: To reformat my Domain Controller and give it bigger hard drives with a new raid configuration. We only have one domain controller.
OPTION: Using another windows server on site to become a secondary Domain Controller, replicate our data, and then reformat the main server. That sounds like the most seamless option, but I wonder if I will have problems with the main server after reformatting it; will it be easy to promote it back to being the main Domain Controller or will some conflict arise with the secondary?
Am I on the right track? If so, what should I be aware of going into this? If not, what would be a better way?
