Moving "Spamassassin " from Warty to Hoary ?

[Vincent Trouilliez]

I installed "Spam assassin" to add spam filtering to Evolution.
It works great, filters 99% of the junk e-mails. But it took him about a
month to learn. 
This was on Warty. I have installed Hoary now, how can I re-use all the
data that Spamassassin learnt in Warty ?
Shall I just re-use the ~/.spamassassin folder ?
