At first the Intentia Application Suite ran just in IBM platforms (AS/400, S/390, etc.), but in middle 1990s Intentia made the decision to carry out a technology shift to a new development environment based on Java, being one of the first ERP vendors to perform this transition. As a consequence of the new technology, the applications were certified on a number of additional operating systems, including Unix in the form of Sun Solaris. For a while Intentia maintained both RPG and Java based applications, even when the current developments and new applications were mainly based on Java.
