This topic article describes how to update an instance of 

Companyname

 to a newer version. To identify the versions of the application being upgraded, see Release Version Numbering. 

Note
If you are running a version of  Companyname with a release date prior to 2017_01 or 2019_01, you must install a minimum required version of  Companyname  before you can upgrade to the current version.

Process Overview

In general, the update process has the following steps:

1. Backup Back up everything that should be backed up. This may might include KBs, software code, database files, etc., depending on what is to be updated. See Set Up Knowledgebase Backups.
2. Obtain new licenses for the new release, if it is a major upgrade with a new main version number. See Licensing.
3. Run the Setup Assistant to replace installed software and/or data that should be updated. See Setup Assistant.
Roll back to pre-update state if something goes wrong. See Rolling Back.
5. Perform the upgrade.

For moderately sized KBs, the process is simple because the installer includes an option to create a full backup, and it automatically executes a set of integrity checks after the upgrade. In the rare case that something goes wrong and the system can't repair itself, it automatically rolls back to the pre-update state using the backup.

Regardless of KB size, the upgrade itself is typically quick. In larger KBs, the overall process can take a long time due to the time required to create a backup.

Tip
For in-house systems, and for more information about creating backups more easily for large KBs, see Upgrading In-House Systems.

Update Methods

There are three ways to run the update process:

• Online Update. This uses an online connection to download and install the newest version of 

  Companyname

  . This is the simplest method, provided you have a stable internet connection.
• Manual Update. You download the installation files and install them locally. This option is preferred if your connection is unstable, or if you want to minimize the potential for errors.Command Line Utility EWUpdate
• EWUpdate Command Line Utility. This option is generally not necessary, but it can be useful for advanced functions, or in situations where the online and manual methods are unsuccessful.

Preparing to Upgrade

Before you upgrade on a Windows server:

• Open the command prompt as an Administrator and restart the

  Companyname

   services. This clears up any long-waiting threads in the application or database process that might affect the upgrade. Here is an example of the command to use: C:\Agiloft\bin\ew-control.exe -a restart
• Sign all other users out of that Windows server, aside from the user that runs the upgrade. This prevents other Windows users from interfering with the upgrade process, particularly while restarting services or accessing files and folders.

Backup database data using OS-level backup	-k,--skiposlevel	This command only applies if the built-in MySQL server is used. Under normal circumstances a full OS-level backup is made.   Use this option to skip the default OS-level backup of the MySQL directory. No database restoration will be is possible if the upgrade fails.
Skip checkers unless any patchers were run	-p,--scup	When the application server starts, it performs data checks for consistency; data checking may take , which might take a long time. Use this option to skip data checking if no data was changed on update. This may can speed the time taken to start the application server starting.
Skip project backup if possible	-K,--skipprjbckp	At the very beginning of the update process all existing projects are saved to the backup directory. If this option is set then no project backup is performed, if allowed. Project backup is required in some update modesSome update modes require a project backup, in which case it isn't skipped.

Rolling Back

If the upgrade fails due to any problem, the setup will halt with an error message, and roll back to its former state. It should retain all your settings. The error will provide you with the installer logs, which you can use , the system automatically troubleshoots problems and applies the proper fixes. If the upgrade still fails, the system prompts the user for input before rolling back to the pre-update version. All your settings are retained, and the logs are copied to <Agiloft-Home>\logs\ so you can use them to trace the cause of the upgrade failure to and resolve it before trying the upgrade again.
