Need to expand space on a 2000 server VM

Hello, I havent had to do this in a while.  I have a client that is running 2 Vmware 3.5 ESXi Update 4 servers. 

They need to expand the space on one of there old 2000 server VM. 

Ive used vmware converter int he past but havent used it in about 2 or 3 years so im having trouble remembering things.

Such as, will vmware converter work with a 2000 server vm or is that to old?

The idea would be to convert the 2000 server vm and in the process expand the D drive with more space.  I have plenty of space in my vmware storage. 

But I cant remember, does the converter process do any kind of sysprep on it?  im not sure if they have any of the old product keys for this. 

Thanks for any help

Mike
