+~~~~~~~~~~~~~~~~~~~~~~~~~~

+Xena continuous traffic by default does a 3 second learning preemption to allow

+=====================
+Upgrading vswitchperf
+=====================
+
+Generic
+-------
+
+In case, that VSPERF is cloned from git repository, then it is easy to
+upgrade it to the newest stable version or to the development version.
+
+You could get a list of stable releases by ``git`` command. It is necessary
+to update local git repository first.
+
+**NOTE:** Git commands must be executed from directory, where VSPERF repository
+was cloned, e.g. ``vswitchperf``.
+
+Update of local git repository:
+
+.. code:: bash
+
+ $ git pull
+
+List of stable releases:
+
+.. code:: bash
+
+ $ git tag
+
+ brahmaputra.1.0
+ colorado.1.0
+ colorado.2.0
+ colorado.3.0
+ danube.1.0
+
+You could select which stable release should be used. For example, select ``danube.1.0``:
+
+.. code:: bash
+
+ $ git checkout danube.1.0
+
+
+Development version of VSPERF can be selected by:
+
+.. code:: bash
+
+ $ git checkout master
+
+Colorado to Danube upgrade notes
+--------------------------------
+
+Obsoleted features
+~~~~~~~~~~~~~~~~~~
+
+Support of vHost Cuse interface has been removed in Danube release. It means,
+that it is not possible to select ``QemuDpdkVhostCuse`` as a VNF anymore. Option
+``QemuDpdkVhostUser`` should be used instead. Please check you configuration files
+and definition of your testcases for any occurrence of:
+
+.. code:: python
+
+ VNF = "QemuDpdkVhostCuse"
+
+or
+
+.. code:: python
+
+ "VNF" : "QemuDpdkVhostCuse"
+
+In case that ``QemuDpdkVhostCuse`` is found, it must be modified to ``QemuDpdkVhostUser``.
+
+**NOTE:** In case that execution of VSPERF is automated by scripts (e.g. for
+CI purposes), then these scripts must be checked and updated too. It means,
+that any occurrence of:
+
+.. code:: bash
+
+ ./vsperf --vnf QemuDpdkVhostCuse
+
+must be updated to:
+
+.. code:: bash
+
+ ./vsperf --vnf QemuDpdkVhostUser
+
+Configuration
+~~~~~~~~~~~~~
+
+Several configuration changes were introduced during Danube release. The most
+important changes are discussed below.
+
+Paths to DPDK, OVS and QEMU
+===========================
+
+VSPERF uses external tools for proper testcase execution. Thus it is important
+to properly configure paths to these tools. In case that tools are installed
+by installation scripts and are located inside ``./src`` directory inside
+VSPERF home, then no changes are needed. On the other hand, if path settings
+was changed by custom configuration file, then it is required to update configuration
+accordingly. Please check your configuration files for following configuration
+options:
+
+.. code:: bash
+
+ OVS_DIR
+ OVS_DIR_VANILLA
+ OVS_DIR_USER
+ OVS_DIR_CUSE
+
+ RTE_SDK_USER
+ RTE_SDK_CUSE
+
+ QEMU_DIR
+ QEMU_DIR_USER
+ QEMU_DIR_CUSE
+ QEMU_BIN
+
+In case that any of these options is defined, then configuration must be updated.
+All paths to the tools are now stored inside ``PATHS`` dictionary. Please
+refer to the paths-documentation_ and update your configuration where necessary.
+
+.. _paths-documentation: http://artifacts.opnfv.org/vswitchperf/docs/index.html#configuration-of-paths-dictionary
+
+Configuration change via CLI
+============================
+
+In previous releases it was possible to modify selected configuration options
+(mostly VNF specific) via command line interface, i.e. by ``--test-params``
+argument. This concept has been generalized in Danube release and it is
+possible to modify any configuration parameter via CLI or via **Parameters**
+section of the testcase definition. Old configuration options were obsoleted
+and it is required to specify configuration parameter name in the same form
+as it is defined inside configuration file, i.e. in uppercase. Please
+refer to the overriding-parameters-documentation_ for additional details.
+
+**NOTE:** In case that execution of VSPERF is automated by scripts (e.g. for
+CI purposes), then these scripts must be checked and updated too. It means,
+that any occurrence of
+
+.. code:: bash
+
+ guest_loopback
+ vanilla_tgen_port1_ip
+ vanilla_tgen_port1_mac
+ vanilla_tgen_port2_ip
+ vanilla_tgen_port2_mac
+ tunnel_type
+
+shall be changed to the uppercase form and data type of entered values must
+match to data types of original values from configuration files.
+
+In case that ``guest_nic1_name`` or ``guest_nic2_name`` is changed,
+then new dictionary ``GUEST_NICS`` must be modified accordingly.
+Please see guest-configuration_ and ``conf/04_vnf.conf`` for additional
+details.
+
+.. _overriding-parameters-documentation: http://artifacts.opnfv.org/vswitchperf/docs/index.html#overriding-values-defined-in-configuration-files
+.. _guest-configuration: http://artifacts.opnfv.org/vswitchperf/docs/index.html#configuration-of-guest-options
+
+Traffic configuration via CLI
+=============================
+
+In previous releases it was possible to modify selected attributes of generated
+traffic via command line interface. This concept has been enhanced in Danube
+release and it is now possible to modify all traffic specific options via
+CLI or by ``TRAFFIC`` dictionary in configuration file. Detailed description
+is available at configuration-of-traffic-dictionary_ section of documentation.
+
+Please check your automated scripts for VSPERF execution for following CLI
+parameters and update them according to the documentation:
+
+.. code:: bash
+
+ bidir
+ duration
+ frame_rate
+ iload
+ lossrate
+ multistream
+ pkt_sizes
+ pre-installed_flows
+ rfc2544_tests
+ stream_type
+ traffic_type
