+# `update:db`
+
+Update Database -- Runs ExpressionEngine database updates only
+
+Use this command when your ExpressionEngine files are already in place and you only need to run database update steps.
+
+## Syntax
+
+`php eecli.php update:db`
+
+## Options list:
+
+```
+    --rollback
+        Rollback last database update
+
+    --verbose
+    -v
+        Verbose output
+
+    -y
+        Skip all confirmations. Advanced use only.
+
+    --skip-cleanup
+        Skip cleanup steps after update
+
+    --to-version=<value>
+        Target database version to upgrade to
+
+    --from-version=<value>
+        Starting database version to upgrade from
+```
+
+## Examples:
+
+`php eecli.php update:db`
+
+`php eecli.php update:db --from-version=7.5.0 --to-version=7.5.3 -y`
+
+`php eecli.php update:db --rollback -y`
+
+## Operational caveats
+
+- `--to-version` cannot be greater than your installed app version.
+- If your database is already at or above the target version, the command exits without running updates.
+- If `--from-version` does not match the detected database version, the command prints a warning before continuing.
+- When running against a local installer payload, `EE_INSTALL_MODE` must be set to `TRUE` in `.env.php`.
+
+## Rollback notes
+
+- Rollback requires a backup SQL file at `system/user/cache/ee_update/database.sql`.
+- If that backup file does not exist, rollback cannot run.
