- 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.
