Yes, you can continue to use DataPipe 3 client even though DataPipe 7 was released in September 2025.

DataPipe 7 Server is a ‘secured’ version of DataPipe 3 Server.  They are different products and can run side-by-side on the same computer.

DataPipe 3 is not encrypted.  DataPipe 7 encrypts both communications and data at rest and therefore DataPipe 7 requires a certificate.  See KB372 for more information on DataPipe certificates.
