Question for upgrading

[Egoitz Aurrekoetxea]

Hi mate, 

I think (and say think :) )I finally found a method. Although I'm
testing it deeply... it seems (say seems too :) ) 2.4 is compatible with
a mail spool in 2.3 (at least with my config). 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 :) :) 

Cheers!
