Has anyone looked at using replication as a migration method? If
replication can be setup in such a way that you can replicate from an
old version to a new version, you can use that to build the new version
of the database on a seperate machine/instance while the old version is
still live. With some sophisticated middleware, you could theoretically
migrate without any downtime.
