My recently purchased R500 came with FW 188.8.131.52.53, can I go right to 184.108.40.206.62 or do I have to go to 220.127.116.11.55 first? Release notes and this post say upgrade to 18.104.22.168.62 from 22.214.171.124.55 or 126.96.36.199.608.
I'm an NPI engineer for Unleashed, and helped with testing/QA. Unleashed started with 188.8.131.52.608. We did beta testing with 184.108.40.206.38 -.53, but officially updated the production server to 220.127.116.11.55. There might have been some APs in the line that loaded .53, but version .55 is what you'll receive today. Please let me know your results if you do an Administer&Services->Administer->Upgrade today.
