I'm trying to migrate IP address data from our Access database over to IPAM. I'm doing so by moving the data into excel, adjusting the fields to reflect the correct values (Device Type specifically), matching the columns with that of IPAM's categories, and the saving as a CSV format. When I import, it says successful but it seems to be leaving out some data. Some IP's have the correct detail information but others are still blank. Am I doing something wrong?
