I don't know, perhaps you never read our wiki ?

You can only have one PDC in an NT4-style domain, but you can have
multiple BDC's, in AD it is different, all DC's are equal (except for
the FSMO roles and they can be on any DC) and it is recommended to run
multiple AD DC's. You also cannot run your old PDC in your new AD
domain, it would be ignored and worse, once your clients have seen an AD
DC, they will never use the PDC again, even if you turn off all AD DC's.
