+Upgrading to Airflow 2.0+
+-------------------------
+
+.. contents:: :local:
+
+Apache Airflow 2.0 is a major release and the purpose of this document is to assist
+users to migrate from Airflow 1.10.x to Airflow 2.0.
+
+Step 1: Upgrade to Python 3
+'''''''''''''''''''''''''''
+
+Airflow 1.10 will be the last release series to support Python 2. Airflow 2.0.0 will require Python 3.6+.
+
+If you have a specific task that still requires Python 2 then you can use the PythonVirtualenvOperator for this.
+
+For a list of breaking changes between Python 2 and Python 3, please refer to this
+[handy blog](https://blog.couchbase.com/tips-and-tricks-for-upgrading-from-python-2-to-python-3/)
+from the CouchBaseDB team.
+
+
+Step 2: Upgrade to Airflow 1.10.14 (a.k.a our "bridge" release)
+'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+To minimize friction for users upgrading from Airflow 1.10 to Airflow 2.0 and beyond, a "bridge"
+release and final 1.10 version will be made available. Airflow 1.10.14 includes support for various critical features
+that make it easy for users to test DAGs and make sure they are as compatible with Airflow 2.0, so that the . We strongly recommend that all users upgrading to Airflow 2.0 first
