+ 0 Votes hi markp24 3 years ago Are you saing you cant use a BDC ? or your cant do a backup of the DC? you can make read only DC's which will work. To migrate to a DC you need to migrate the Schema and other master roles to the new DC (vs prooting a bdc to a pdc)i hope that helps + 0 Votes Reponse To Answer gavinjinks 3 years ago Hi, Thanks for the swift reply. What im trying to imply is that I have never used a BDC before, also, if its not the best way of backing up our DC, then what is?I only have two other servers in our domain: a W2k3 and W2k file servers, is it feasable to use these as BDC's?
