The first thing to understand is that Linux or BSD distributions are independent development. They do not attempt to be free and open-source copies of any proprietary operating system you might know. Therefore, a new user needs to be open to learn a different system without the expectation that everything works the way as one is used to. Depending of the choosen operating system the learning curve can be quite steep.
Changes are always difficult: they contain risks, but also provide opportunities. There are two critical success factors that need to be addressed:
We can help you to achieve these goals and make your switching to Linux / BSD a success story.
Provision of knowledge about Linux / BSDs that enables you make decisions
Assistance during the installation process
Support and maintenance of the running system
Problem-solving when something goes wrong
Selection of applications that run on Linux / BSDs
