You can purchase the Migration pack which essentially breaks all the
restrictions/limitations of SBS, but you still only wind up with Standard
Version not Enterprise
And CALs do not carry forward, you would have to purchase all new cals
Otherwise purchase the Server version you want, make it a DC, transfer any
data, then shut down SBS and seize the FSMO roles to the new server
