Any self-hosted Strapi project can be hosted on Strapi Cloud. The migration process from self-hosted to Cloud will heavily depend on your Strapi version, database and asset storage setup. If you are currently participating in our beta, what you’ll need to do is create an account and link your GitHub repository with a new Strapi Cloud project.
Support for GitLab / Bitbucket repositories will come in Q2 or Q3 2023.
For additional information about migration we urge you to reach out to our sales team at email@example.com and we will schedule a call with one of our Account Executives / Managers as there are significant differences in terms of pricing and support coverage. In short, Strapi Cloud pricing is usage-based as opposed to our Self-Hosted Enterprise Edition which is user-based.
