Migrating Google Drive Comments

By default 'Migrate File Comments' is disabled and any implications must be considered before enabling this setting. It is recommended that you first test this option.

The 'Migrate File Comments' setting allows for the migration of Google Document comments which are listed in 'Table 1'. Comments added to Microsoft Office and PDF files are embedded in the documents and will be migrated when performing a 'Drive' migration.

At the time of creating this article the Google API has the following restrictions :

  2. Disabling comment notifications is not supported and email notifications will be sent in the following cases
