Apparently some people need to hear this so here we go: doctrine/orm 3 is compatible with doctrine/dbal 3, so it should be possible for you to upgrade to doctrine/orm 3, test and deploy, let things run for a few days and then upgrade to doctrine/dbal 4 instead of upgrading both packages at once. Also, if you use doctrine/orm is mentioned in your composer.json, but not doctrine/dbal, you're probably doing it wrong.
