6.1.Read folders directly
Configure an Import source connector, pointing to the folder or Zip file, where the mailboxes to be migrated are exported.
In How to treat files? pick Migrate folders to mailboxes. contentGATE will recognize the top-level folders as entities (i.e. mailboxes) and treat them like source mailboxes (with or without deeper folder structure). The email files are usually the result of an export from a system, for example a legacy archive one.
The export might be already finished, meaning that all emails are already in the base folder. In this case the migration can be performed immediately without any limitations.
There might be situations when the export is not finished yet, meaning that new email files are exported continuously. In this case the migration must be planned carefully. contentGATE allows a continuous migration also in this situation, but some actions need to be taken multiple times based on the availability of the exported data.
The general rule is that the content of the base folder should not be changed: no files should be deleted or moved, however, new files and folders can be added. The migration is picking up only the files which were not migrated yet – this is called delta migration. If continuous export is used, the migration can be performed parallel to the export. It is necessary to run the delta migration after the export is definitely finished.
