Upgrade path for ICX7450 (currect version SPS08030e and SPS08030k

Hello,I’m planning to upgrade my ICX switches (I have a bunch of them). They are at versions 08030e and 08030k. I’m new in brocade technology and I’m trying to figure it out how to choose the version for the upgrade. I saw the last version 0807 is supported by my switches, but I’m not sure if I can upgrade directly to that or if I have to follow a sequence of upgrades to finally install the last version. Can some one highlight me on this, please?Thanks in advance for your help
