I think I followed it all, except for step 3. How do I feed the data into the new database? Would you be able to expand that a little?

No experience with HW, but transfering available data to a new database should be standard. 1: Create the new database, make sure to set "--start" slightly earlier than the oldest data you're going to insert. 2: Tune the new RRD so that it accepts gauge data (no matter the real DS types). Also set the heartbeat to a high number, at least as high as the largest step*steps in your RRAs. 3: Use rrdtool fetch to get data out of the original RRD. Feed this data into the new RRD 4: Tune the RRD back to its original settings. Step 3 may involve a couple of substeps, depending on the resolution of your RRAs. Make sure you understand data consolidation and you'll know what to do.
