In my environments, i have 1 Zone data collector(most preferred) and 1 backup ZDC(preferred). And remaining servers are default ZDC. For maintenance purpose i will reboot and disjoin the primary ZDC from domain on production hour. So i would like to now whether my backup ZDC(preferred) will work as primary ZDC or not?? my backup ZDC also host one application which can load upto 30 users. Do i need any other steps to do?? Kindly suggest.
