+# Upgrade to 3.x General Notes
+
+We recommend you upgrade to DBAL 3 first before upgrading to ORM 3. See
+the DBAL upgrade docs: https://github.com/doctrine/dbal/blob/3.10.x/UPGRADE.md
+
+Rather than doing several major upgrades at once, we recommend you do the following:
+
+- upgrade to DBAL 3
+- deploy and monitor
+- upgrade to ORM 3
+- deploy and monitor
+- upgrade to DBAL 4
+- deploy and monitor
+
+If you are using Symfony, the recommended minimal Doctrine Bundle version is 2.15
+to run with ORM 3.
+
+At this point, we recommend upgrading to PHP 8.4 first and then directly from
+ORM 2.19 to 3.5 and up so that you can skip the lazy ghost proxy generation
+and directly start using native lazy objects.

+Sometimes we may want to log or trace the raw SQL being generated from its DQL
+for profiling slow queries afterwards or audit queries that changed many rows
+``$query->getSQL()`` will give us the prepared statement being passed to database
+with all values of SQL parameters being replaced by positional ``?`` or named ``:name``
