WordPress Multisite is a powerful and game changing tool for many businesses. That being said, it may not be the perfect solution for every business that thinks they need it. You need to carefully evaluate your needs to determine whether it’s the right fit for your business.
If you do go ahead with installing it, keep in mind that management (beyond adding sites, activating themes and plugins) can get quite complex. Reversing a decision to separate sites and migrating a Multisite can cause major headaches. So again, carefully evaluate your need for it before activating it.
