A date for your diary. On Wednesday, April 17 at 7:00 AM PDT (UTC-7) / 10:00 AM EDT (UTC-4) Percona’s PostgreSQL Support Technical Lead, Avinash Vallarapu and Senior Support Engineers, Fernando Laudares, Jobin Augustine and Nickolay Ihalainen, will demonstrate the upgrade of a legacy version of PostgreSQL to a newer version, using built-in as well as open source tools. In the lead up to the live webinar, we’ll be publishing a series of five blog posts that will help you to understand the solutions available to perform a PostgreSQL upgrade.
Synopsis
Are you stuck with an application that is using an older version PostgreSQL which is no longer supported? Are you looking for the methods available to upgrade a legacy version PostgreSQL cluster (< PostgreSQL 9.3)? Are you searching for solutions that could upgrade your PostgreSQL with a minimalistic downtime? Are you afraid that your application may not work with latest PostgreSQL versions as it was built on a legacy version, a few years ago? Do you want to confirm if you are doing your PostgreSQL upgrades the right way ? Do you think that you need to buy an enterprise license to minimize the downtime involved in upgrades?
Then we suggest you to subscribe to our webinar, that should answer most of your questions around PostgreSQL upgrades.
This webinar starts with a list of solutions that are built-in to PostgreSQL to help us upgrade a legacy version of PostgreSQL with minimal downtime. The advantages of choosing such methods will also be discussed. You’ll notice a list of prerequisites for each solution, reducing the scope of possible mistakes. It’s important to minimize downtime when upgrading from an older version of PostgreSQL server. Therefore, we will present three open source solutions that will help us either to minimize or to completely avoid downtime.
Our presentation will show the full process of upgrading a set of PostgreSQL servers to the latest available version. Furthermore, we’ll show the pros and cons for each of the methods we employed.
The webinar programme
Topics covered in this webinar will include:
- PostgreSQL upgrade using pg_dump/pg_restore (with downtime)
- PostgreSQL upgrade using pg_dumpall (with downtime)
- Continuous replication from a legacy PostgreSQL version to a newer version using Slony.
- Replication between major PostgreSQL versions using Logical Replication.
- Fast upgrade of legacy PostgreSQL with minimum downtime.
In the 45 minute session, we’ll walk you through the methods and demonstrate some of the methods you may find useful in your database environment. We’ll see how simple and quick it is to perform the upgrade using our approach.
