How to change Drobo FS IP address without wiping data

I set up my Drobo FS a few months ago, but now I need to change its IP address. When I log in to the Drobo Dashboard as Administrator, I am unable to access the IP address settings. The links that would get me there are greyed out.

Does anyone know of a way to change an IP address for a Drobo FS that is no longer in the factory default state without pinhole resetting or otherwise wiping the data already on the hard drives?

Product: Drobo FS
Firmware Version: 1.2.6
Software Version: 2.5.3
Operating System: Windows 7

Thank you.
