As noted in the ticket, with a lot of data, some of the queries can take an exceptional amount of time. This can generally be reduced by optimizing MySQL's (and your disk's) I/O and MySQL's configuration, but that has to be done before any sort of upgrade starts. (And it should probably be done a staging server as you'll need to experiment.)
