    Know what breaks before you migrate

    Analyze a MySQL or MariaDB schema before moving to PostgreSQL — 20 deterministic checks, run entirely in your browser.

    MySQL / MariaDB

    Version is auto-detected from your schema — no need to pick it.

    Sample schema

    Drag & drop a .sql file, or

    Basic analysis runs in your browser. Your schema is not uploaded for the standard scan — no database password required.

    Need a safe export? mysqldump --no-data --routines --triggers --events DATABASE > schema.sql

    What this checks

    20 deterministic rules across types, table options, indexes, defaults/triggers, identifiers, functions, and scheduling — every one documented with a dedicated migration guide. Nothing here is AI-generated prose about your schema; every finding traces back to a specific, tested detection rule.

    FAQ

    How do I check my MySQL/MariaDB version?

    The database itself is always the most reliable source — connect with any client and run:

    SELECT VERSION();
    • Mac: mysql --version in Terminal for a Homebrew install, or check the MySQL pane in System Settings for the official installer.
    • Windows: mysql --version in Command Prompt if the client is on PATH, or open MySQL Workbench — the version is shown on the connection's home screen.
    • Linux: mysql --version for the client, or check the installed server package — dpkg -l | grep -E 'mysql-server|mariadb-server' on Debian/Ubuntu, rpm -qa | grep -E 'mysql|mariadb' on RHEL/Fedora.
    • Managed/cloud (RDS, Cloud SQL, PlanetScale, etc.): the engine version is shown directly on the instance's configuration page in the provider's console.

    Easiest of all: export with mysqldump as suggested above, and the version is embedded automatically in the dump's header comments — DevEquiv detects it for you, no manual lookup needed.

    How do I check my PostgreSQL version to pick the right Target?

    Connect with psql or any SQL client and run:

    SELECT version();
    • Mac: psql --version in Terminal for a Homebrew install, or check the Postgres.app menu-bar icon if you're using it.
    • Windows: psql --version in Command Prompt, or open pgAdmin and check the server's Dashboard/Properties tab.
    • Linux: psql --version for the client, or pg_lsclusters on Debian/Ubuntu to list every installed cluster and its version.
    • Managed/cloud (RDS, Cloud SQL, Supabase, Neon, etc.): shown directly on the instance's configuration page in the provider's console.

    Pick whichever version you're actually migrating to. If you're standing up a brand-new PostgreSQL instance and haven't decided yet, the newest version your hosting option supports usually gives the longest support window.
