Thing is, at FM our production servers more or less track the master branch, so we were running "3.0" from the moment 2.5 forked off, and so our upgrade process only ever really needs to deal with iterative changes.  Our accumulated experience is what informs the "upgrade notes" included with the 2.5.0 and 3.0.0 releases (not sure about older versions, I wasn't around then).

So I'll try to upgrade first to 2.4 and later to 3.0 setting up a replication from 2.4 to 3.0. Would be fine if Bron, Ellie or someone at Fastmail could tell something about it to us :) :)
