Depending on whether you need your current database or not, there are two different approaches you can use:
If you do not need your current database, uninstall the old Magic Collaboration Studio version and install a new one as described in Upgrading Teamwork Cloud.
If you need the current database, migrate it as described in Migrating database. Note that there are several migration strategies you can use. After migrating the database and upgrading Magic Collaboration Studio, you must update your projects as well.
