Looks like Fortinet removed the Cookbook's upgrade path table from public access and are advising to use their upgrade path calculator on support.fortinet.com. However, the calculator will only display upgrade paths from v5.2.9 and does not even include v5.4.8. I cannot find a cached version of the Cookbook table anywhere.
I understand the firmware's release notes include verbiage concerning upgrade paths but this is not efficient whatsoever. Ex. I have a 100D on v5.2.4 and need to get it to v5.2.13. Based on the release notes from all the various v5.2.x builds, I would have to upgrade the 100D from v5.2.4 >> v5.2.6 >> 5.2.8 >> 5.2.9 >> 5.2.11 >> 5.2.13!
Does anyone have a saved/cached version of the Cookbook upgrade path table?!
