How Can I Make My PowerShell Scripts Compatible Across Different Versions?

Have you considered just setting the required version for PowerShell in your scripts? If your coworkers refuse to install PowerShell 7, it might help to make it clear why it would benefit them. Also, are you using specific modules with dependencies that might require the newer version? Importing scripts into your module is definitely possible, but you need to ensure that all the necessary files are correctly referenced! You can compile requirements in your manifest file to manage dependencies better.

For cross-platform compatibility, there's not much shortcut other than thorough testing. Fortunately, PowerShell 5 syntax works in 7, so try to stick to it where possible. But keep in mind that file paths differ between Linux and Windows, which could cause issues. If you're looking for a good module layout, check out the ModuleBuilder module; it offers a structured way to manage everything and even helps with merging your files into a single module. Also, ensure your manifest files are set up correctly if you're going that route!
