Troubleshooting Migration

  • [アーティクル]

This topic describes the migration log files, common messages that may appear in the migration log files, and provides solutions for issues that you might encounter.

Migration Log Files

The following log files are created every time that the migration wizard is run:

  • CS2007Upgrade(060801 160908).log

  • ExceptionOrders.log

By default, both files are created in the %temp% folder (for example, <drive>:\Documents and Settings\<user>\Local Settings\Temp). You can specify an alternative location for the log files in the initial pages of the migration wizard.

Note

CS2007Upgrade.log is updated with new logging information every time that you run the Upgrade Wizard, whereas ExceptionOrders.log is overwritten. Therefore, you must review ExceptionOrders.log before you run the Upgrade Wizard again. The log file names contain a timestamp that displays the year, month, day, and time in 24-hour time. For example, "060801 160908" indicates August 1, 2006 at 16:09:08. The ExceptionOrders log file is only created if orders (Transaction resource) are migrated. The default name and location of the file can be changed on the "Orders Configuration Settings" page in the upgrade wizard.

Migration Error Messages

Most migration errors result from database column or type mismatches, or from duplicate files or databases in the target location. The following sections list some frequently encountered messages.

System.TimeoutException

If you encounter a System.TimeoutException error when you migrate the Transaction resource, do the following to set an environment variable to reduce the batch size used when you migrate:

  1. On the computer where you run the Upgrade Wizard, create a Windows environment variable named PurchaseOrderBatchSize.

  2. Set the value of the variable lower than the default value of 2000 (for example, set it to 1000 or 500).

  3. Run the Upgrade Wizard again and migrate the Transactions resource.

Column PurchaseOrders.Name referenced in orders storage mapping file has different precision than the corresponding entry in the SQL schema.

This error occurs when the mapping in the orders storage mapping file is incorrectly specified.

Warning: Unable to load the Configuration Data for the site 'CSharpSite'. This site will be skipped for migration.

This error occurs when there is a site that has more than one application in Commerce Server 2002 Standard Edition.

If the applications are Web services from Commerce Server 2002 Feature Pack 1, remove them from the site and use the Pup package included with Commerce Server 2007 to add the Web service applications to the site. If you have modified any of the Web services, you will have to re-apply the modifications to the updated Web service applications.
