The person migrating the project will need to use Paratext 8 to migrate it. Paratext 9 does not have the ability to migrate Paratext 7 projects. But once the project is migrated, everyone on the team can work in the project in Paratext 9. There is no need to migrate a project from Paratext 8 to 9, migration is only needed when going from Paratext 7 to 8 or 9.

In preparation for moving to Paratext 8, a certain number of active projects in Paratext 7 were registered in Paratext 8, including the users then active in the Paratext 7 project. This creates a conflict when a new administrator in the Paratext 7 project attempts to migrate. His Paratext 8 does not see the existing registration because his name was not included in the registration. He cannot submit a new registration because it conflicts with the old one.  The person listed as the project administrator in the registry can add the new administrator on the project members page of the registry, this will cause the new admin’s Paratext 8 to recognize the project as registered and permit him to continue the migration. Paratext 8, like Paratext 7 will accept multiple projects with the same name, but will not accept multiple projects with the same name and the same users.
