Merging RRD Graphs
Due to old and failing hardware, I decided to upgrade my hardware. I took a backup, built a new PFsense, restored the backup, and made all the necessary configuration changes for the old configuration to work on the new hardware (New network interfaces etc.). Unfortunately it was a couple of weeks before I swapped over the machines. I am now missing those two weeks of RRD graph data. Is there a relatively simple way form me to merge the RDD data from the old box to the new box without the potential to screw things up?
Thanks in advance
Relatively simple, probably not. If you're familiar with RRD and comfortable with the BSD command line, this script might do it for you:
Most people just toss the old data.
