Solaris Transition Guide

Advantages of Migrating to the Solaris Operating Environment

The UNIX® standard, SVR4, accommodates the leading UNIX variants (System V, BSD, SunOSTM, and XENIX), uniting the majority of the installed base of UNIX users. The Solaris operating environment, based on SVR4, gives software developers, system administrators, and end users the benefits of a standard operating system including broad compatibility, a growth path, and reduced time to market. It also delivers a functional and powerful product reflecting years of refinement. Among the many advantages the Solaris operating environment provides are portability, scalability, interoperability, and compatibility.

Although the foundation of the Solaris operating environment is based on SVR4, extensive functionality has been added in areas such as symmetric multiprocessing with multithreads, real-time functionality, increased security, and improved system administration.

The Solaris operating environment offers the following features:

Portability, Scalability, Interoperability, and Compatibility

The Solaris operating environment is portable, scalable, interoperable, and compatible.


The SunOS 5.7 product is portable across multiple vendor platforms. Software conforming to an application binary interface (ABI) runs as shrink-wrapped software on all vendor systems with the same microprocessor architecture. This enables application developers to reduce software development costs and bring products to market quickly, and enables users to upgrade hardware while retaining their software applications and minimizing conversion costs.


Over time, applications become more widely used and require more powerful systems to support them. To operate in a growing environment, software must be able to run in a wide power range and must be able to take advantage of the additional processing power. The Solaris operating environment runs on machines of all sizes, from laptops to supercomputers.


Heterogenous computing environments are a reality today. Users purchase systems from many vendors to implement the solutions they need. Standardization and clear interfaces are critical to a heterogeneous environment, enabling users to develop strategies for communicating throughout their network.


Computing technology continues to advance rapidly, but the need to remain competitive requires vendors to minimize their costs and to maximize their investments. As new technology is introduced, there is a need for the existing software investment to be preserved.

Advantages for Large Organizations

The Solaris operating environment provides a number of sound business reasons for transitioning to an industry-standard-based UNIX operating system. Application development and maintenance costs are lower, and application portability is enhanced.
