In order to select a source company, it is necessary that the destination company and the site have been defined. The color code of the Comments field is used to quickly view if these requirements are met: the color green indicates that the company can be migrated.
The companies already migrated appear in the list with a green color code. Any context must be defined in the processed companies, so they cannot be subjected to a new migration; the control over the companies selection is carried out when executing the processing.
