4 steps for planning a database migration project

4 steps for planning a database migration project

Jul 25, 2014

 

Database migrations may be necessary for a number of reasons, including the release of new technologies, system optimization or meeting consolidation needs.

However, the larger the organization, the more complex these projects become, requiring a sophisticated plan to ensure objectives are achieved promptly and with minimal downtime.

Here are four ways to avoid hiccups and give your next database migration initiative a high chance of success.

1. Outline database migration requirements

There are several factors to consider before beginning your migration, such as which databases will be involved and what applications are likely to be affected.

You must also assess whether modifications to applications are required to ensure they run successfully on the new database.

2. Evaluate downtime impact

System downtime typically means lost revenues, a drop in productivity and an inability to access vital business information. Organizations therefore want to avoid crucial systems being unavailable as much as possible.

Judge how much of an effect downtime will have on your business and take steps to minimize the repercussions of a database migration.

For enterprises where downtime simply isn't an option, real-time replication techniques are an attractive investment, as they can lower application outage time to almost zero.

3. Assess resource requirements

Every database migration project requires resources, whether it's time, money or human capital.

Estimate budget constraints, calculate how long it should take and how many employees will be needed to complete and test the migration.

4. Define testing criteria

Database migrations must be tested to gauge the success and accuracy of the project, which is an area that can often be overlooked in some organizations.

Set appropriate parameters for what constitutes adequate testing based on your system requirements and assess stability and application performance.

Once the new database is comprehensively tested, it should now be ready for deployment in the production environment.
