Replicating between different Slony versions?

Hi folks,

I'm working on migrating our database cluster from PostgreSQL 8.1 to
8.3.  I'm following the "dump and restore, then use Slony to
replicate" procedure, to minimize downtime.  The problem is, the new
2.0 version of Slony-I does not support anything prior to 8.3, so I
have to install different versions of Slony-I.

My question is, is this even feasible?  Or would I be better off
installing Slony-I 1.x on my 8.3 cluster, and then upgrading it after
the migration?

I ask first because I am extremely skittish about experimenting with a
production database cluster.  :-)

Thanks,
