Teradata is one of the oldest and most popular database and analytics-software providers there are. Modern analytics owes a lot to Teradata, and the systems and organizational software that they helped to develop. Many corporations have used Teradata as the backbone for their analytics for decades. As a result, many corporations have an astronomical amount of reports stored through Teradata, and still rely on it for their daily work and data source.
But, like any technology, you can’t stay on top forever. What was once innovative about this Relational Database Management System (RDBMS) is now considered somewhat archaic. This has left many organizations going through Teradata migration and switching to a cloud-native environment for data warehousing and advanced analytics.
But with so much information stored on the Teradata system, migrating to the cloud is a pretty monumental task. However, all you really need is an efficient action plan, and that’s what we will outline in this article:
Before we get started, let’s examine the main reason why companies are making the migration off of Teradata. This will help you understand why the move off Teradata is so worth it. Teradata is less than ideal for modern analytics for the following reasons:
As you can see, there are many reasons to migrate from Teradata. Here’s how to make the process as efficient as possible:
As with anything else, a proper plan makes everything run more smoothly. You need to schedule ample time to fully understand the Teradata Enterprise Data Warehouse (EDW), and then understand the ETL pipelines you will need migrate as well.
However, understanding a Teradata EDW in its full complexity is an extremely convoluted and time consuming process. For this reason, we recommend you use automation tools to help plan this migration.
Automation tools hold many benefits in planning a migration, and are quite capable and sophisticated. Benefits include:
Basically, automation helps you to outline and understand your entire migration process, so that you’ll get it right the first time and won’t have to re-do anything once you’ve started. This migration map helps you to fully understand your migration process, and plan how to implement it properly.
So you’ve planned the migration and built the code to get the job done. The final step in migrating the Teradata is to actually test the code. Once again, this process can be done manually or automatically.
Just like above, we don’t recommend manual code testing. Much like manual code translating, manual code testing is prone to human error, is very time-consuming, and is not cost-effective.
Also as above, we definitely recommend automatic code testing. Here are the reasons why:
As you can see, migrating off Teradata is no easy task. It’s a big undertaking, as there is simply so much data to deal with, especially if your company has been dependent on it for years. However, with a proper plan, and efficient use of automation tools, you can make the process cost-efficient, timely, and relatively stress-free. It’s all about planning and execution.
