I talked with Jozef and Tomas right now - and we think it will be good
to discuss this in the Monday OpenFlow Plugin meeting this process
(steps provided by Andy, the process followed by Sam/NetVirt when they
consumed VPN Service into NetVirt, history, etc.). That way we can
ensure it is done right - have all the OpenFlow Plugin committers vote
during the meeting if needed. And then initiate OpenFlow Java vote.
Hence we will greatly appreciate if Andy (Grimberg) and Sam Hague can
join the meeting. The meeting details are here:

Agree with you Ed about having a vote in OpenFlow Java committer
community - and in general the TSC role if we plan to archive. Had
planned on that based on how we have decided to proceed (based on
Tomas's study of impact). Unfortunately I have been offline for
periods of time during the last week or two (on a vacation).
Tomorrow (Wednesday) I will be meeting Jozef Bacigal (OpenFlow Java
& Plugin committer) and Tomas Slusny (OpenFlow Plugin committer
working on this) to understand the latest status on how this has
evolved and based on that will figure out the best course of action
(after discussing with the other OFP/OFJ committers).

This strikes me as good news overall. It might be a
good idea to get a vote from the OpenflowJava Committers,
particularly as they will need to vote to archive the
openflowjava project, and it also makes everything very clear.
As to the TSCs role, it has one for archiving the openflowjava
project, and it would have one if there was some dispute with
the openflowjava committers (which does not appear to be the
case). All of that said, it is probably courteous to inform
the TSC :)
Thank you for guiding this process :)

Thanks Sam! We may have some questions as we go further into
the process.

We kept history when we split ovsdb/netvirt and then
merged netvirt
and vpnservice. The flow Andy used copied all the files
into NetVirt
and the history was kept intact. I think I came up with
the commands
to use and Andy did the work - but I can't find those
emails right

You should also stop the jobs running for the old
openflowjava repo
and migrate them to use openflowplugin repo.

Just move the OpenFlow

OFP documentation?

Yes, this is what we did - just pulled in the relvant
docs to netvirt.
