Thanks. Sound good to me.
Let's remember to send email reminders to the ML just before and just
after it, and put that info in irc's topic of #libreoffice-dev

I'll be around most likely for the end of it (but prolly not at the start :-D)

moggi, vmiklos, bjoern... you may want to keep an eye on the various
'Bots' to irc/bugzilla etc...

PS alex: Let's make _sure_ to keep the rsa host key of the gerrit vm
while migrating :-)
PS2: to all: if your known_host happen to have the ip and not the
hostname for gerrit and/or if you have some extra security that do
track the ip anyway, you may have to tweak things after the migration
as, obviously, the IP of the gerrit server will change.
