Many leading organizations are looking to digitally transform their legacy performance testing systems with an agile system that enables them to shift left. BlazeMeter is a flexible SaaS platform for functional and performance testing that can be integrated into CI/CD pipelines, APMs, and environments. However, the migration process from LoadRunner to BlazeMeter might seem intimidating at first.
To help with the conversion process, this blog post provides four easy steps to help plan, design and execute script migration. To learn more about the scope of such a project and how to get started, check out this whitepaper “LoadRunner to BlazeMeter Migration”.
Back to topLoadRunner to BlazeMeter: Benefits of Script Conversion
Before we dive into the migration process itself, let’s see which advantages companies gain from converting from LoadRunner to BlazeMeter.
Scalability
BlazeMeter enables running load tests in the cloud or on-premise. Organizations can scale their tests across geo-locations and up to hundreds of thousands of users (and even more) to test any use case they need. No need to worry about infrastructure cost and setup or test and report synchronization because BlazeMeter covers it all.
Open-Source Compatibility
BlazeMeter is 100% compatible with open-source JMeter. Developers and testers can create their scripts in JMeter and enjoy all the capabilities and open source community support, and then run their tests in BlazeMeter. In addition, BlazeMeter can become the single location from which all JMeter scripts are easily modified, maintained and executed.
Easy Recording Capabilities
BlazeMeter’s Chrome Extension enables 'on-the-fly' script recording for creating and running test scripts. The recorder works for JMeter, Selenium, Taurus and BlazeMeter.
Advanced Monitoring Capabilities
BlazeMeter provides real time monitoring and reporting capabilities, as well as easy access to historical reports for comparison and trend identification. You can also extend your test data further with top-tier APM solution integrations like AppDynamics, Dynatrace, CA APM, New Relic and CloudWatch. Get end-to-end visibility of your server, application and end user experience. And more.

Now let’s see what a migration process from LoadRunner to BlazeMeter will look like.
Step 1: Determine the Scope
The first step in the migration project is to determine its scope. This will be based on the number of scripts that need to be converted, their complexity, various risk factors, the functionality they’re testing, and more.
Step 2: Decide on the Strategy
When converting to BlazeMeter, there are a number of different approaches to choose from. Companies can either migrate all the scripts at one, choose a step-by-step process in which parts of the testing system are migrated while the other system continues to function, or migrate and run both systems side-by-side.
Step 3: Convert Low-Hanging Fruit with the Shift Left Converter
The ShiftLeft Script Converter enables easy conversion of LoadRunner scripts to JMeter. You only need to drag and drop your zip files into it. Learn more in the whitepaper.
Step 4: Convert the Remaining Scripts
ShiftLeft can handle most LoadRunner scripts. However, there are some features it does not support, like multiple HTTP requests and custom functions. These remaining sections should be manually converted, with the help of a professional services team.
