+Upgrade Instruction from |version_to_upgrade|
+=============================================
+
+
+This section will show you how to upgrade from CloudStack |version_to_upgrade|
to latest
+CloudStack |release|.
+
+Any steps that are hypervisor-specific will be called out with a note.
+
+We recommend reading through this section once or twice before beginning
+your upgrade procedure, and working through it on a test system before
+working on a production system.
+
+.. note::
+ The following upgrade instructions should be performed regardless of
+ hypervisor type.
+
+Overview of Upgrade Steps:
+----------------------------
+
+#. Check any customisations and integrations
+#. Upload the |sysvm64-version| System VM template if not already using it.
+#. Confirm Java 17 is the default Java version
+#. Stop all running management servers
+#. Backup CloudStack database (MySQL)
+#. Upgrade 1st CloudStack management server
+#. Update hypervisors specific dependencies
+#. Restart 1st management server
+#. Check that your upgraded environment works as expected
+#. Upgrade and restart the remaining management servers
+
+
+.. include:: _customisation_warnings.rst
+
+.. include:: _sysvm_templates.rst
+
+.. include:: _java_version.rst
+
+Packages repository
+-------------------
+
+Most users of CloudStack manage the installation and upgrades of
+CloudStack with one of Linux's predominant package systems, RPM or
+APT. This guide assumes you'll be using RPM and Yum (for Red Hat
+Enterprise Linux or CentOS), or APT and Debian packages (for Ubuntu).
+
+Create RPM or Debian packages (as appropriate) and a repository from
+the |release| source, or check the Apache CloudStack downloads page at
+http://cloudstack.apache.org/downloads.html
+for package repositories supplied by community members. You will need
+them for :ref:`ubuntu414` or :ref:`kvm414` hosts upgrade.
+
+Instructions for creating packages from the CloudStack source are in the
+`CloudStack Installation Guide`_.
+
+Database Preparation
+--------------------
+
+Backup current database
+
+#. Stop your management server or servers. Run this on all management
+ server hosts:
+
+ .. parsed-literal::
+
+ $ sudo service cloudstack-management stop
+
+#. If you are running a usage server or usage servers, stop those as well:
+
+ .. parsed-literal::
+
+ $ sudo service cloudstack-usage stop
+
+#. Make a backup of your MySQL database. If you run into any issues or
+ need to roll back the upgrade, this will assist in debugging or
+ restoring your existing environment. You'll be prompted for your
+ password.
+
+ .. parsed-literal::
+
+ $ mysqldump -u root -p -R cloud > cloud-backup_$(date +%Y-%m-%d-%H%M%S)
+ $ mysqldump -u root -p cloud_usage > cloud_usage-backup_$(date
+%Y-%m-%d-%H%M%S)
+
+
+.. _ubuntu414:

+Management Server
+-----------------
+
+Ubuntu
+######
+
+If you are using Ubuntu, follow this procedure to upgrade your packages. If
+not, skip to step :ref:`rhel414`.
+
+.. note::
+ **Community Packages:** This section assumes you're using the community
+ supplied packages for CloudStack. If you've created your own packages and
+ APT repository, substitute your own URL for the ones used in these examples.
+
+The first order of business will be to change the sources list for
+each system with CloudStack packages. This means all management
+servers, and any hosts that have the KVM agent (no changes should
+be necessary for hosts that are running VMware or Xen.)
+
+Edit your ``/etc/apt/sources.list.d/cloudstack.list`` file on
+any systems that have CloudStack packages installed to points to version
|version|
+
+This file should have one line, which contains:
+
+.. parsed-literal::
+
+ deb http://download.cloudstack.org/ubuntu bionic |version|
+
+Setup the public key for the above repository:
+
+.. parsed-literal::
+
+ wget -qO - http://download.cloudstack.org/release.asc | sudo apt-key add -
+
+#. Now update your apt package list:
+
+ .. parsed-literal::
+
+ $ sudo apt-get update
+
+#. Now that you have the repository configured, it's time to upgrade
+ the ``cloudstack-management`` package.
+
+ .. parsed-literal::
+
+ $ sudo apt-get upgrade cloudstack-management
+
+#. If you use CloudStack usage server
+
+ .. parsed-literal::
+
+ $ sudo apt-get upgrade cloudstack-usage
+
+
+.. _rhel414:
+.. _rpm-repo414:
+
+CentOS/RHEL
+##############
+
+If you are using CentOS or RHEL, follow this procedure to upgrade your
+packages. If not, skip to hypervisors section :ref:`upg_hyp_414`.
+
+.. note::
+ **Community Packages:** This section assumes you're using the community
+ supplied packages for CloudStack. If you've created your own packages and
+ yum repository, substitute your own URL for the ones used in these examples.
+
+The first order of business will be to change the yum repository
+for each system with CloudStack packages. This means all
+management servers, and any hosts that have the KVM agent (no changes
+should be necessary for hosts that are running VMware or Xen.)
+
+Change your ``/etc/yum.repos.d/cloudstack.repo`` file on
+any systems that have CloudStack packages installed to points to version
|version|.
+
+This file should have content similar to the following:
+
+.. parsed-literal::
+
+ [apache-cloudstack]
+ name=Apache CloudStack
+ baseurl=http://download.cloudstack.org/centos/$releasever/|version|/
+ enabled=1
+ gpgcheck=0
+
+Setup the GPG public key if you wish to enable ``gpgcheck=1``:
+
+.. parsed-literal::
+
+ rpm --import http://download.cloudstack.org/RPM-GPG-KEY
+
+#. Now that you have the repository configured, it's time to upgrade the
+ ``cloudstack-management``.
+
+ .. parsed-literal::
+
+ $ sudo yum upgrade cloudstack-management
+
+#. If you use CloudStack usage server
+
+ .. parsed-literal::
+
+ $ sudo yum upgrade cloudstack-usage
