Depending on the complexity of the data, it might be as simple as exporting the data as a CSV, then using the Data Import Wizard, or slightly more complicated, by way of the Apex Data Loader. Both tools require the data in particular formats, which you can read about in the related help topics for each of the above links.
If that ends up being too complicated, you might start looking on the AppExchange. As long as you can get the CSV data, there are lots of options on the AppExchange. Please note that you'll need to do your own research here, as we don't do product recommendations.
Finally, doing a simple search on the internet for "migrating dynamics crm data to salesforce" should yield a lot of useful results. For example, there are some applications that can connect to both systems and act as a two-way bridge for the data. There are various costs (usually subscription-based or volume-based), so you will need to do research for the product(s) that suit your needs and are within your budget.
There is no "one right way" to do migration, and what works for me or someone else might not work for you, so if you do decide to purchase/subscribe to a service, make sure you research a few alternatives first. It is entirely possible to migrate all your data for free, but the Data Import Wizard and Apex Data Loader takes some time to learn and get used to; if you just want to "get it done," you're probably going to have to pay someone for the service.
