Upgrading Postgres version

["Tony Fernandez" <Tony.Fernandez@xxxxxxxxxxxxxx>]

Hello all,

 

I am in the process of updating my DB on Postgres 8.1.11 to 8.3.4.  I also use Slony 1.2.14 for replication.

 

Is there a safe path on how to accomplish this, please advice on what steps I will need to consider.  Bear in mind that I am planning to skip from Postgres 8.1.x to 8.3.x and I use Slony to replicate my production DB into two more boxes simultaneously.

 

Thanks,

 

Tony Fernandez
