Merge

Due to various acquisitions we have 3 different The Dude instances/servers that we would like to MERGE to one server. Some are 6.37 some are 4.03. Any tools out there for this. Each has hundreds of Devices, lots of Maps, links, and various settings.

Creating new Maps and links are not impossible. However, adding all the devices and settings for thousands of devices would be a full time job for weeks.

Ideas? Hints?
