Porting Enterprise Apps from UNIX to Linux

Decide on a Viable Operating Environment

Key to the planning process is determining to which distribution of Linux the application is to be ported. You should make sure that all of the required software is available for the level to which you planning to port. For example, it may not be possible to release a middleware product for the Linux 2.6 distribution, because a key third-party database used in the most typical configuration is not available on that same distribution. The initial offering of your product or application might have to be based on a Linux 2.4 distribution instead.
It's also possible that some of the software with which the application interacts may not be available for all distributions or architectures for which the application is intended. Make a careful study of the viability of your chosen operating environment.
Another issue to consider is whether the application is going to be 32- or 64-bit and whether it is going to coexist with other third-party software that could also operate in a 32- or 64-bit mode.
