regarding roles for data migration

Hi all,

i want to give permissions only for data migration in roles.can any one explain, after ceating the role when i was tested it is given one message like you dont have read permission for table information table,please contact your administrator.

Hi,

You need to grant access for some forms that those migrators will be using (or dataports etc) .

How will they do the migration? What objects will they use to execute it ?
