Upgrade 14.3 to 14.4

Introduction

Goal

Upgrade a Bloomreach Experience Manager implementation project from version 14.3.x to 14.4.y.

Upgrade Method

When upgrading from the most recent previous version (14.3.3), the rolling update method is supported for deploying the upgraded 14.4.0 project.

In all other scenarios, rolling update is not supported and a stop-start update method (such as blue-green) must be used for deploying the upgraded 14.4.0 project.

Experience Pages were introduced in 14.3. In 14.4.0, support for inheritance of Experience Page Layouts has been added.

See Experience Page Layouts Configuration for details.
