For those that upgraded, any risks of functionality breaking?
One concern I have is whether VPN users certificates will change and need re-enrollment?
If you're upgrading from 18.5.2 MR2 and performing antispam filtering be aware that the antispam engine has been upgraded to SASI and the detection rates are truly abysmal. Wait for 19.0.1 MR1 and hope…
I have an update from 18.5 MR3 to 19.0. After that the LACP connection with SFP+ doesn't work anymore with my Dell S4048 switcht. I'm also waiting for an answer from support.
check for Auto Negotiation. Set it, if not set.
Auto Negotiation is set.LACP link with Firmware 18.5 MR3 works well.
You could try to disable it and check, if the Links are online or not.
