Hi

Thanks for the info, so when you say upgrade from TMOS to Next, do you mean we can just upgrade our LTMs from there current version to a version running Next like we would a normal upgrade procedure?

Also, I see info on something called F5OS, is this another version of software, or another way of saying F5 Big IP Next ?

F5OS is the software running on rseries and velos hardware. It is actually a hypervisor, similar approach as VCMP.

On top of F5OS you run tenants. These tenants can be either TMOS or Next.

 

As for the TMOS to Next upgrade, F5 says that it will be a simple version upgrade with possible fallback downgrade also.
