NT to Windows 2000 server migration

Does anyone have a good solution for this scenario?

I have a NT PDC.
I have a plain Windows 2000 member server with no AD on it.

I cannot simply upgrade the NT PDC to W2K Server because the bloody C: partition is too small. I don’t have software available that can resize the partition on the fly. Partition Magic doesn’t work either on servers.

I was thinking of creating a BDC, promoting that first, demoting the PDC. Then upgrade the BDC to Win2K and finally DCPROMO the W2K Member server to become DC. Does that sound ok?

Someone suggested I ghost the NT PDC and repartition it when I restore the image but I’ve never done that before.

Any suggestions?
