Can you offer me some advice when setting up an environment for porting my Unix apps to Linux?

It is important to perform the appropriate capacity planning, in order to architect a system that will be able to support the current Unix workloads you are using, without over-architecting a solution. Here are some tips:
  • Try to use industry standard benchmarks where possible in doing this.
  • The environment should come with suitable compilers that will allow you to recompile programs.
  • Don't be shy with providing extra disk space to the environment, since you will be making adjustments.
  • Ask questions of your ISV regarding best practices for Linux configurations. Your ISV should be a big asset to you in your migration. Make sure there are customers already using their Linux based software; don't be the guinea pig!
  • Don't forget to train your staff in Linux. There are enough differences between Unix and Linux to warrant training. If possible, buy support from your Linux distributor, as there will be issues that come up that require escalation.

I would also suggest setting up multiple environments, including a sandbox where you may play around without harming your development and prototype-production environments.
