exporting Usersnames Profiles to new PDC

Bring it online as a BDC. When everything is running fine with it as a BDC, then:

1. Turn off the old PDC.
2. On the new PDC (currently a BDC), go into Server Manager.
3. Promote the new machine to PDC.

Good luck,

Hi, your bdc will have a read-only copy of all your user profiles. So you can take your current PDC offline and promote your BDC to PDC status. Then bring the new PDC online and demote the existing PDC to BDC (what it was before). You can then sync your domain through server manager. The only downside to this is that synchronization can be time-intensive if you have a lot of users. Otherwise, it's pretty straightforward. There is also basic instructions in server manager help.
Good luck.

I would have to go with answer number 1(partly).Only problem with answer 2 is you CANNOT demote a PDC. You can however reinstall the OS on your new PDC, make it a BDC during installation, then when it has synced up, you can promote it to a PDC in server manager by going to Computer menu, then choose Promote to Primary Domain Controller. Hope it helps

The previous answers will work for your users but you have a lot of other issues to take into account in replacing a PDC such as your shares, security on the NTFS volumes, print queues, etc. The link below is provided by Andrew S. Baker, one of my NT heroes, on his website. Browse around and check out his other helpful suggestions and links. This specific link concerns rebuilding a PDC with some common pitfalls to avoid: (also check out the link at the bottom of that page for new hardware.)

By the way, you CAN demote a PDC to a BDC -- see the following Microsoft article:
