IPAM

I have customer that we deployed Northstar for their internal ip management over 8 yrs ago. They are still using it, but it is slowly breaking on them. Can someone recommend an IPAM solution that has a Northstar import option? They have hundreds of entries detailing customer who was assigned the ip address and I would like to avoid any data massaging.
