A migration typically fails during the Fortinet configuration file upload or during the push of the migrated configuration to management center.

Some of the common scenarios where the migration process fails are:

• Unknown or invalid characters in the Fortinet configuration file

• Incomplete or missing elements in the Fortinet configuration file

• Loss of network connectivity or latency

If your Fortinet configuration file fails to upload, the reason is that the Secure Firewall migration tool could not parse one or more lines in the file.

You can find information about the errors that caused the upload and parsing failure in the following locations:

• Error message displayed by the Secure Firewall migration tool—Provides a high-level summary of what caused the failure.

• Pre-Migration Report—Review the Configuration Lines with Errors section to see which lines in the Fortinet configuration file caused the failure.

• Log file—Search on the word "error" to view the reason for the failure.

• Unparsed file—Look at the end of the file to identify the last ignored line of the Fortinet configuration file that was successfully parsed.
