February 2022, Optimizely released version 12.4.0 CMS Core packages (Minor version release), with no breaking changes in APIs. You’re contemplating the pros and cons of updating your website to Optimizely Content Cloud (CMS) Version 12 and Commerce Cloud Version 14.

According to a Forrester study, a composite business experienced a 286% return on investment (ROI) and $1.5 million in savings over three years, owing to higher developer productivity and enhanced site performance on Optimizely DXP.

Why are we talking about upgrading?

Optimizely DXP is currently built on Microsoft’s .Net framework, which Microsoft is phasing out with the release of .Net 6. Built upon Microsoft’s .NET Core branch of .NET, .Net 6 represents a complete rewrite of the platform without technical debt, focusing on performance modernization and cross-platform support.

All products built on the .Net framework must migrate eventually – Microsoft will no longer invest in research and development in previous versions, creating risk and performance issues over time for those who don’t migrate.

As a Leader in 2022 Gartner Magic Quadrant for Digital Experience Platforms Report, Optimizely stays at the forefront of technical innovation to offer customers the most powerful digital experience platform.

The newest releases of both Optimizely CMS V12 and Commerce Cloud V14 include a core code update to .Net 6 to continue leveraging Microsoft’s modern architecture and maximize this important technical partnership.

So, the performance of .NET 6 is better than that of its predecessors, and it is not surprising that the CMS upgrade also brings significant performance increases.

This customizable feature for headless deployment allows you to integrate your Optimizely CMS 12 website with numerous applications such as ecommerce, translations connector, and more. REST APIs were built to facilitate compatibility between applications built in a different technology than ASP.NET. This means code can be written once for various uses and applications, making it a flexible, efficient, and effective solution.

You can move your legacy front-end presentation layer to native Optimizely SDK (React SDK, VueJS SDK, ASP.NET SDK) for headless implementation. This will help make the front end fast, new feature implementation, and seamless rollouts.
