Gerrit migration on June 19th

Hello,

Alex, Robert and I plan to do a smooth migration from LXC to KVM based 
virtual machines. Steps involved are recreating all production VMs in 
KVM in parallel (we have enough IPs available), then shutting down LXC, 
then upgrading the host system. Luckily, with KVM, the base OS and 
kernel of the guest does not need to fit the one of the host.

For working on the gerrit migration, we have scheduled

        Wednesday, June 19th,
        at about 1600 UTC

Depending on how far we get, we'd directly switch the machines on that 
evening.

Is there any critical blocker for the above timetable?

Florian
