The first that you need to do is to prepare a data model for Cassandra - this is the crucial step in your journey (I recommend to take DS201 & DS220 courses on DataStax Academy).

When you have data model ready, you can perform migration. You can use some of the existing tools:

DSBulk - you can export data from Mongo as CSV or JSON, and import into Cassandra using DSBulk (DataStax blog has a series of blog posts on DSBulk, I listed them at the end of answer)
Spark - you can read data from Mongo using corresponding connector, and load data into Cassandra using Spark Cassandra Connector. (You can run Spark in the local master mode)

P.S. Blog posts on DSBulk:
