Migrate Postgres 7.2 to Postgres 8.1

["Marin Alonso, David" <dmarin@xxxxxxxxxxxxxxxx>]

Hi all

 

All people have advised me that I should migrate my database Postgres 7.2.2

 

PostgreSQL 7.2.2 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2 20020903 (

Red Hat Linux 8.0 3.2-7)

 

to new version 8.1.4.

 

I have downloaded

• postgresql-8.1.4-1PGDG.i686.rpm
• postgresql-contrib-8.1.4-1PGDG.i686.rpm
• postgresql-server-8.1.4-1PGDG.i686.rpm
• postgresql-libs-8.1.4-1PGDG.i686.rpm

I have done backup from databases before installing, but I don´t know what are the steps to migrate to new version?

 

 

Somebody could tell me what are the steps or where I can find information about these kind of migrations

 

Thanks in advance
