Migrating from Selenium RC to Selenium Web Driver is easy if your test scripts are re-factored and use the page object model.
Migrating from QTP to Selenium Web Driver is also not very complicated as explained by Tarun Lalwani (QTP expert and author of QuickTest Professional Unplugged) in this Sauce Labs webinar.
There are multiple benefits of going through this conversion, most notable being:
- faster execution time (90% faster Selenium scripts in the case study)
- no language dependency
- cheaper test automation environment
- cloud services available (Sauce Labs)
- free tool
- more browsers supported
