This topic describes how to update an instance of to a newer version. To identify the versions of the application being upgraded, see Release Version Numbering.
If you are running a version of with a release date prior to 2015_02 you must upgrade to the 2017_01 release before installing a later version.
In general, the update process has the following steps:
There are three ways to run the update process:
The online update option is the simplest method.
If an earlier release of is already installed, you can update the software by simply downloading and installing the latest version. The latest official release of can be found at https://www.agiloft.com/ewdownload.
Run the downloaded installer. The installer will detect an existing instance and prompt the user about a possible update.
Confirm the selection in the Update Options screen, and the installer will walk you through the upgrade.
Update options allow the user to set certain update process details. When performing an update in web GUI mode, you can change the default options on the update options page, shown below:
The update options here are explained in more detail in Command line options. You should exercise caution with these commands if you are not certain of their operation, particularly if you are working on a live system.
The ewupdate command line utility performs an update with all default options if run without any arguments. Use the –help option to print a short help screen. If you wish to use the command line updater with non-default options, use the command line arguments listed below.
These options are also available using the ewupdate utility. Default options can be changed using the command-line options listed, which correspond to the options presented in web GUI mode. The list below consists of the most commonly and recommended options.
Corresponding ewupdate command-line option
Backup database data using OS-level backup
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 possible if the upgrade fails.
Skip checkers unless any patchers were run
When the application server starts it performs data checks for consistency; data checking may take a long time. Use this option to skip data checking if no data was changed on update. This may speed the application server starting.
Skip project backup if possible
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 modes.
Don't delete temporary files after update
Upon update, temporary files are normally stored on the hard drive. These may include data backups, unpacked new code, etc. By default, temporary files are removed after an update. If this option is set then temporary files are left on the device and will only be deleted before the next update.
Don't backup temporary files - logs etc
If this option is set then no temporary files such as log files are backed up before the update. This saves used disk space and shortens elapsed time.
For additional update options, use the –help command to print a list of commands.
Example: ewupdate --stable -s,--stable Download stable release version (Offical Release) -l,--latest Download latest release version (Beta) -d,--devel Download development version (Alpha) -C,--custom <host> Download from custom server -F,--file <file> Upgrade from a distribution that has already been downloaded to the local hard drive -f,--force Unattended update, all prompts are answered 'yes' -c,--caution Unattended update, all prompts are answered 'no' -k,--skiposlevel Skip OS level backup (avoid using this when skipping project backup) -K,--skipprjbckp Skip project backups (avoid using this when skipping OS level backup) -t,--keeptemp Keep temp files -p,--scup Skip checkers unless patchers were run -i,--backuptemp Backup temporary files such as logs (when unattended mode) -r,--requiredspace <Gb> Disk space (Gb) required for update (use with care) -w,--warn <MMM or MMM:NNN> Displays a warning message to customers about an impending update. Argument syntax is MMM or MMM:NNN, where MMM is the number of minutes before update and NNN is the estimated update duration in minutes -A,--allowsameversion Do update even if new version is same as old one -X,--forceincompat Forces an upgrade between releases that should not be compatible. Do not use this option. -v,--verbose Print error details -h,--help Prints this help
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 to trace the cause of the upgrade failure to resolve it before trying the upgrade again.
