https://www.sugarcrm.com/crm/support into your local machine. .
https://www.sugarcrm.com/crm/support into your local machine. .
Log into the Sugar application to use the Upgrade Wizard. Run a PHP script from the command line on the server where the Sugar instance is installed to use the Silent Upgrader.
|
CAUTION:
|
It is strongly recommended that you run the upgrade process on a copy of your production system.
|
Prerequisites for Upgrading SugarCRM
|
•
|
Backup your current Sugar directory and database before beginning the upgrade process.
|
|
•
|
Disable op-code caching before upgrading your Sugar installation if op-code caching is enabled in the PHP configuration file. You can enable it after the upgrade process is complete.
|
|
•
|
Increase the default value of the parameters listed below before you begin the upgrade process if you are using Zend Core 2.0:
|
|
¢
|
Navigate to C:\Program Files\Zend\Core\etc\fastcgi.conf and increase the default value for ConnectionTimeout to 3000 seconds and RequestTimeout to 6000 seconds.
|
|
¢
|
Navigate to the php.ini file and increase the default value of max_execution_time to 6000 seconds.
|
|
•
|
Perform the following for the large size of the upgrade files:
|
|
¢
|
Modify and save the value of Maximum upload size to 21000000 (20MB) in the Advanced section of the System Settings page of your current Sugar installation.
|
|
¢
|
Navigate to the php.ini file on your web server and configure the parameters listed below in the Advanced section of the System Settings page of your current Sugar installation:
|
|
l
|
Set post_max_size to at least 60MB
|
|
l
|
Set upload_max_filesize settings to at least 60MB
|
|
l
|
Set max_input_time to a large number
|
|
l
|
Set memory_limit to 256MB
|
Restart the web server and begin the upgrade process.
|
•
|
Ensure that LimitRequestBody is set to a large number or use the default value of 2GB if you are using an Apache web server and LimitRequestBody is set in the httpd.conf file. Restart Apache and begin the upgrade process.
|
|
•
|
Ensure that the webserver user has write permissions to the Sugar database. The upgrade to Sugar 6.3 will add and replace files in several locations including the Sugar root directory. The webserver user must have write permissions for the root folder and all sub-directories during the upgrade process.
|
|
•
|
The process of upgrading can take up to 30 minutes. Set the CGI script timeout to more than the default 300 seconds to ensure that the CGI application does not time out if you are using the IIS web server.
|
|
•
|
Save PHP files for customized modules (for example, accounts.php) in the Customs directory and not within the main module. Existing customizations may be overridden by changes in Sugar 6.3 during upgrade.
|
Things to Consider when upgrading SugarCRM
The Dynamic Teams feature requires some database schema changes across all modules as part of the upgrade process. For larger databases, this operation can take some time to complete. Follow the steps listed below to ensure a smooth upgrade process:
|
1.
|
Test your upgrade on a development instance instead of the production instance.
|
|
2.
|
Use the Silent Upgrade method through the command line interface to conduct the upgrade instead of the Upgrade Wizard inside the application if your database contains more than 10000 records per table.
|
|
3.
|
Log into the application as an Administrator and use the Repair option to repair and rebuild the database after the upgrade is complete.
|

During the upgrade process, Sugar performs a three-way merge between the customized instance on old version, default instance on old version, and default instance on new version. This three-way merge adds any fields that have been added to the default module layouts in the new version to the corresponding module layouts in the existing version, if the module layouts in the old version were not customized through Studio (or in the appropriate upgrade-safe way) prior to the upgrade. The three-way merge also changes the placement of fields in non-Studio-customized module layouts to match the placement in the default module layouts.
Sugar displays the Confirm Layouts page as Step 5 of the upgrade process if the existing module layouts have been customized, and there are changes to the default fields and field placement in the new module layouts.
The Confirm Layouts page lists the module layouts that have changed in the new version. The administrator has the option of applying the changes to the existing module layouts. By default, all of the listed module layouts are selected to be merged during the upgrade.
For example, in 6.1.0, Sugar added the Assigned To fields to the default Detail View and Edit View layouts for Notes and for Email Templates. If the instance being upgraded has a customized EditView layout for Notes, but no customized layouts for Email Templates, the following will occur during the upgrade:
|
a.
|
The Confirm Layouts page appears as Step 5 in the Upgrade Wizard
|
|
b.
|
The Confirm Layouts page displays the Notes module with the EditView and DetailView layouts. The Email Templates layouts do not display on the Confirm Layouts page because the existing layouts were not customized.
|
|
c.
|
The Administrator has the option of choosing to merge the changes in the Notes module with the existing customized EditView layout.
|
|
11.
|
Uncheck the module if you do not want to add the new fields to a module.
|
|
12.
|
Click Next.
|
This displays a message confirming that the layouts were successfully merged (if you chose to update your modules).
|
13.
|

|
|

16.
|
Click Repair and select the Rebuild Relationships and Rebuild Extensions options in the Systems panel of the Administration Home page.
|
For more information, see Repair.
|
17.
|
Manually merge the files by extracting the skipped file from the patch zip file if you unchecked any files to prevent the Upgrade Wizard from overwriting them. Merge the file installed in the Sugar application directory.
|
|
Note:
|
Check the upgradeWizard.log file in the Sugar folder for information on unsuccessful Sugar upgrades.
|
