Netflow Relocation to Different Drive

Hi all -- Our Netflow server was recently virtualized. The standalone server it was originally configured on had nearly a TB on the system ( c: ) drive where Netflow was installed. Since the virtualization the system drive space was reduced to only 20MB and nearly immediately caused Netflow space problems. Our server management group has allocated an additional partition with more than enough space but I need to know how to move Netflow and or it's data to that disk partition. Must I perform a backup of the data and do a reinstall on the new partition and restore the data? Your insights are greatly appreciated. Cheers.
