ISSS Legacy System Data Migration


For clients who have previously used another SEVIS batching solution, implementation of Terra Dotta's ISSS software may include copying important student records from the legacy system to the new TDS site.

All TDS sites contain tools for admins to manually create records and upload documents and additional information to those records. This manual process doesn't require IT support or incur any professional service fees, but it may be time-consuming for the functional office to create and update a large volume of historical records.

Terra Dotta offers a one-time professional service to migrate student and scholar data from the legacy SEVIS batching system to the new TDS site.

For more information, and to secure a price quote, contact your Terra Dotta representative.


Client will extract data from their ISSM database and securely transfer the resulting delimited text file(s) via SFTP. Terra Dotta can assist in providing the necessary queries to extract the required data.

Terra Dotta will import the data so that it will be associated with the corresponding user ID in the Terra Dotta system.

Standard and Optional Fields

Standard Fields

  • Notes
  • Tasks
  • Attached and SEVIS-returned Documents

Optional Fields

Any data for which the legacy system is the source of truth may be included in the migration. Examples of optional fields that clients have migrated include:

  • Orientation and check-in information
  • Agent name and contact information
  • Custom fields in ISSM

Population for Migration

Standard Population

F-1, M-1 and J-1 students and scholars with corresponding active and initial SEVIS records

Optional Population

F-1, M-1 and J-1 students and scholars from previous years may be migrated for an additional cost.

Additional populations of other visa types, such as H-1,TN, O-1, E-2, R-1, B-1/B-2, etc. may be migrated for an additional cost. Migration would include creation of a basic user profile with relevant notes and documents, unless detailed specifics of additional data fields are given.

Migration from Additional Legacy Systems

Data and documents from additional legacy systems (such as ApplicationXtender, etc.) may be included for an additional cost. Cost will be based on volume of data and documents that client needs to migrate.


The migration of data will typically begin at the time the Terra Dotta system goes live. This timing assures that data in the legacy system is no longer being modified. The standard migration project typically takes 1-2 weeks from the time the data is provided to Terra Dotta.

If client would like to expand the scope of the data migration beyond the Standard Active and Initial F-1/M-1/J-1 populations and/or to include additional data points, this will result in additional cost and will extend the required timeline to complete the project.
