Background
SCO Unix is still used by millions around the world. Many still use the Open Server platform as an application server. Intech have many customers on Open Server systems and still actively support the platform and continue to develop under SCO.

Linux is now accepted as a suitable platform for business solutions - particularly for application and web servers. It is very similar to SCO Unix and other flavours of Unix. Intech staff develop and maintain systems on both platforms.

Why Change?
Linux is under active development and offers many new features and facilities. It is available from a number of distributors and can be freely copied. The source code is available if the need arises. Many applications and packages can be obtained under an Open Source license and are often better than some of their commercial competitors.

How Do I Change?
There is an application binary interface module under Linux. This allows SCO binaries to run under Linux. They often appear to run faster than under SCO! Most standard applications will port easily in this way. Some applications with low level interfaces may not port easily but most applications will. Typically you would :-

• Set up a test platform under Linux and copy your environment including directories, permissions, accounts, start up and close down scripts etc.
• Copy across your application binaries and a full system test.
• Roll out the new platform to your user base - but continue to develop under SCO.
• At the completion of the roll out switch development to Linux.
