Important

Before the migration, sure to backup the database.

Sometimes you have to migrate your face biometric data (facens) to another facen model. This usually happens when you decide to update to the latest version of the product.

To migrate to a different facen model, use the findface-sf-api-migrate utility. To pass migration settings, launch it with the -config option and provide a configuration file shown in the example below.

findface-sf-api-migrate -config <migration.ini>

Example of the configuration file:

extraction-api:
  timeouts:
    connect: 5s
    response_header: 30s
    overall: 35s
    idle_connection: 0s
