Data Migration Tool (DMT) accesses OneSpan Authentication Server via a SEAL connection. For the data migration to be successful, the SEAL communicator must be enabled in the OneSpan Authentication Server configuration. The SEAL communicator is always enabled on OneSpan Authentication Server Appliance.
Furthermore, at least one of the OneSpan Authentication Server SEAL ports must NOT be SSL-encrypted. Data Migration Tool uses such ports to connect to OneSpan Authentication Server.
To be GDPR-compliant, we recommend to set up a VPN tunnel between Data Migration Tool and OneSpan Authentication Server to secure the connection.
