  Software product line techniques encourage the reuse and adaptation of
software components for creating customized products or software systems. These
different product variants have commonalities and differences, which are
managed by variability modeling. Over the past three decades, both academia and
industry have developed numerous variability modeling methods, each with its
own advantages and disadvantages. Many of these methods have demonstrated their
utility within specific domains or applications. However, comprehending the
capabilities and differences among these approaches to pinpoint the most
suitable one for a particular use case remains challenging. Thus, new modeling
techniques and tailored tools for handling variability are frequently created.
Transitioning between variability models through transformations from different
approaches can help in understanding the benefits and drawbacks of different
modeling approaches. However, implementing such transformations presents
challenges, such as semantic preservation and avoiding information loss.
TRAVART is a tool that helps with transitioning between different approaches by
enabling the transformation of variability models into other variability models
of different types. This paper discusses the challenges for such
transformations between UVL and IVML. It also presents a one-way transformation
from the UVL to IVML with as little information loss as possible.
