I have removed my PDC and taken it to another location to be the PDC there and I am trying to promote my BDC to my PDC in my current location but I dont' know how and what cautions I need to take.

The only caution I know of is that both the PDC and BDC need to be on the same service pack level. Also, of course, you want to be sure to have a full backup of the machine, including the registry and SAM, just in case. Usually, you would want to promote the BDC before removing the PDC from the network, but if you have already removed the PDC, you should still be able to promote the BDC. This won't cause you any problems provided that you don't intend to put the original PDC back on the network later on. All you need to do is go to Server Manager, highlight the BDC and then click Computer/Promote to Primary Domain Controller. Hope this helps!

A precaution - do not EVER, connect the two remote sites together. Both PDC's will refuse to acknowledge the existence of the other. Did this once and the results were not pretty. Destroyed two domains instead of just one.
