In the following period I have to migrate the AD over to 2008 schema level.
I currently have a x64 Windows 2008 R2 domain controller and one x32 Windows Server 2003 domain controller. The x32 server is a old machine which doesn't even support the upgrade to 2008. I have began my transition plan and installed 2 servers (one with 2008 R2 x64 and one with x64 2003). No problem with transferring the roles, but I can't seem to be able to transfer the Certificate Authority (CA) over to a x64 machine.
1.1. Upgrade the AD schema to 2008.
2.1. I can't use the old root server as it doesn't support Windows Server 2008.
2.2. I have to get to x64 as Windows Server 2008 R2 doesn't support x32.
2.3. I have to move the CA because I have to demote the server.
What I've done so far for the CA move
3.1. Installed a x64 2008 R2, tried to make the restore of the CA there -not working. It should work, but it doesn't according to this TechNet.Error message "Restore of an incremental image cannot be performed before you perform restore from a full image. The directory name is invalid. 0x8007010b (WIN32/HTTP:267) "
3.2. Installed a x64 2003, tried to make the restore of the CA not working because the database is in a different format.
Any ideas would be greatly appreciated, as a last resort I can keep the CA there, but to keep a server only for a CA role seems pointless.
