hi,

i'm running a slony 1.2.21 cluster. the master postgres server has 
postgres version 8.3.9 on i386 architecture. slave nodes mostly have 
postgres 8.3.x, one has 8.4.x

would it be possible to do the following:

- stop write access to master server

- stop all slons

- pg_dump master database

- shut old physical master server down

- load the dump in a 8.4 postgres server with slony 1.2.21 on x86_64 
architecture with same network address as old physical master

- start slons again

- enable write access to new physical master and continue with replication

?

thx for advice
matthias
