Switching between object storage tools is generally possible but involves migration effort: exporting your data or configuration from Cloudflare R2, re-importing or reconfiguring in MinIO, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test MinIO on a non-production project first before migrating.
