There will be a downtime period in the next few days to do the final switchover, but I won't know when that will be until the preliminary copying is done. I am trying not to kill the master completely, but there have been some slave disconnects due to the load already this morning. I'll let everyone know when the downtime will be once I know. 

The copying of data will take days at the rate we're going, and the server is exhibiting some strange memory paging in the process. I am going to reboot the server and try copying with the buildbot master down. The master will be down for about 15m, if I can't get the copy done in that time I will schedule a longer downtime at a better time. Sorry for the churn.
