what do you mean by saying "We tried to upgrade from an older version but there is NO WAY to move the data."? IPAM does not loose information on upgrade.
And there is an import/export function. Granted, it has some deficiencies since it doesn't preserve groups schemes, but it definitely can import massive numbers of subnets and the info for each address in those subnets. I used it to migrate over almost a thousand subnets of info earlier this Summer.
I think some things need to be clarified. The only IPs that count toward the license are:
- Used Addresses
- Reserved Addresses (The reserved subnet source IP and broadcast IPs are excluded from this count)
- Transient Addresses
What version are you trying to upgrade from/to? You should not be losing data performing an upgrade. As far as import/export functionality is concerned, IPAM definitely has this capability. mesverrum is correct. It doesn't preserve group schemes, but we have a fix for that. If you are having trouble with importing/exporting, let me know and we'll be happy to help!
