The following guide will walk through the process of upgrading from a Chariot MQTT Server version 2.0.0 to a newer version. 

Due to the updated method of system backup/restore released in 2.1.0.

Upgrading Chariot MQTT Server

and then to the newer version.

The following upgrade instructions assumes for each of the supported platforms Linux and Windows requires the user has superuser/admin privileges and can execute any scripts at the command line in the directories where these servers are installed. The upgrade process itself consists of two main steps:

1. Run the export script on the old install to create an upgrade file
2. Run the import script on the new install to import the upgrade file

The scripts come packaged with the Chariot MQTT Server version 2.1.0 and can be found in the install directory.

Linux - Upgrading Chariot MQTT Server

1. Following the Licensing Procedure, deactivate your existing license on the v2.0.0 Chariot MQTT Server.
   
   

2. Stop the v2.0.0 Chariot service. From a command prompt, run the Chariot service stop script in the v2.0.0 directory.

   Code Block
   sudo /etc/init.d/chariot stop

   
   

3. Install v2.1.0 following the Chariot MQTT Server Installation instructions. This instance should be installed ONLY and should not be started.

   Warning
   Do not overwrite the old version of Chariot when extracting the Chariot ZIP package, but instead create a new Chariot directory and extract the new Chariot package into that new directory. For example: Old version of Chariot is installed in /opt/chariotv2.0.0 New version of Chariot should be installed in /opt/chariotv2.1.0

   directory to the

   base directory where

   v2.0.0

   was installed

   directory. For example:

   Code Block
   sudo cp ./chariotv2.1.0/upgradeExport.sh ./chariotv2.0.0/upgradeExport.sh

   Code Block
   sudo ./upgradeExport.sh

   
   

4. Copy the

   exported

   upgrade.tgz file from the v2.0.0

   install

   directory to the

   base directory where

   v2.1.0 directory. For example:

   Code Block
   sudo mv ./chariotv2.0.0/chariot_upgrade_20220113_1612.tgz ./chariotv2.1.0/chariot_upgrade_20220113_1612.tgz

   
   

5. From a command prompt, run theupgradeImport script in the v2.1.0

   is installed
6. Run the upgradeImport.sh script to import the file into the new installation

7. Start the new v2.1.0 Chariot MQTT Server.

The new Chariot MQTT Server should be loaded with the Users, Roles, MQTT Credentials, and System & Server configurations from the old installation.  However, the new Chariot MQTT Server will still need to be licensed and any SSL certificates/keys will need to be uploaded again.

Note: Remember to first deactivate the Chariot License on the old server before installing and activating on the new server.

Upgrading on Windows

The following instructions can be used with upgrading the Chariot MQTT Server on Windows.

1. directory referencing the upgrade.tgz file

   Code Block
   sudo ./upgradeImport.sh chariot_upgrade_20220113_1612.tgz

   
   

2. Start the v2.1.0 Chariot service. From a command prompt, run the Chariot service startscript in the v2.1.0 directory

   Code Block
   sudo /etc/init.d/chariot start

   
   

3. Clear your web browser cache after upgrading Chariot to pick up the latest Chariot UI features and updates.

For example: Old version of Chariot is installed in /opt/chariotv2.1.0 New version of Chariot should be installed in /opt/chariotv2.*.*

   
   

9. Start the new Chariot service. From a command prompt, run the Chariot service start script in the v2.*.* directory.

   Code Block
   sudo /etc/init.d/chariot start

   
   

10. Clear your web browser cache after upgrading Chariot to pick up the latest Chariot UI features and updates.
