Hi,

Do we want to bump the compute RPC to 6.0 in Victoria?
Like it or not, fast-forward upgrades where one or more releases are skipped is something we have to live with and take into account. What would be the FFWD upgrade implications of bumping RPC to 6.0 in Victoria, specifically for someone upgrading from Train to W or later?
My understanding is that during FFU you stop both the control plane and the compute services. If you need rolling upgrade of computes then you cannot do FFU but you have to roll forward one release at a time. Cheers, gibi
We did not have the full view what we can gain[2] with such bump so Stephen and I searched through nova and collected the things we could clean up [1] eventually if we bump the compute RPC to 6.0 in Victoria.
I can work on the RPC 6.0 patch during V and I think I can also help in with the possible cleanups later.
Cheers, gibi
