We planned and tested a migration from 2003 to 2012 R2, but unfortunately we hit the issue documented
here despite being fully patched. It was fine in the test environment but not in production.
In the hopes of circumventing this issue we have decided to upgrade to 2008 R2 and then 2012 R2. After demoting the 2012 R2 server we are left with a 2003 domain with a 2012 R2 schema.
I understand that schemas are backwards compatible, so can I simply skip 2008's adprep and crack on as usual?
