Hi List;

We're preparing to do an upgrade from 8.2.5 to 8.3.4 on a system where  
we loose money if it's down - thus downtime is not an option.

I plan to do this:


1) setup a new 8.3.x cluster.
2) install SLONY on the old 8.2 cluster and the new 8.3.x cluster
3) Create/setup a SLONY replication set between the  two clusters (the  
old 8.2 cluster/db as the master and the 8.3.x cluster as the slave)
4) Initialize/start replication
5) Wait for replication to complete
6) Modify / create a 'switchover' script that also moves the  
connections (via an I.P. alias)
7) execute a switchover

My question is this:

Once I get to this point we want to remove SLONY completely, while  
leaving the new 8.3.4 master in place as the only server in read/write  
mode.

Do I execute a drop node ? If so, can I execute a drop node on the  
master ?
Or is there a better approach ?

Thanks in advance..
