windows 2003 domain on parallels desktop 8

Hello,

as my old Dell running windows 2003 with active directory is too much old i would like to migrate into a vm to running on mac mini with parallels desktop 8.

Do you think that i will get issues to run windows 2003 with AD ?
consider that i've also other 2 windows server machine that replicates AD in two lan through vpn connections.

if i can, could be an economic way to run win2003 in vm mode and reduce from another hardware.

What do you think about it? suggestions?
Thanks,

Luca
