There are no immediate plans to support seamless upgrades across major
versions.

In general only upgrades between patch versions (e.g. 3.0.x to 3.0.y)
can be performed without downtime. The exceptions are that 3.1.4 and
3.1.5 are not compatible with other older 3.1.x versions in the same
cluster, and 3.0.0 is not compatible with newer versions from the 3.0.x
series.
