For Upgrading Exchange 2007 I should upgrade forest and domain functional level ..... RRS feed

  • Question

  • Hi

    I have an exchange server 2007 sp1 and I want to upgrade it to Exchange server 2013

    I read Microsoft help and now my rod map is upgrade the forest and domain functional level first.

    I have an old win 2003 DC and 2 win 2008 DC, all of them are DNS server and GC.
    I want to upgrade the forest and domain functional level.
    so I decided to demote this 2003 DC but at the first step I took an error message "Before you can install or remove Active Directory , you must remove Certificate services ..."

    I checked the certificate Authority on this DC but this service is stopped!!
    We have just a certificate on Exchange server not on this 2003 server(DC)!!!

    Now I don't know what should I do!!!??
    Is it possible to demote this DC!? and how!??

    Thank you so much
    Regards
    Mahnaz
