The launch was described as a “important phase’, which allows for the verification of the new platform technology in a live environment.
It is for selected staff and will allow the firm to “further validate system functionality, processes and controls.”
Quilter says activity has begun on a limited basis and will expand further over the next few months ahead of a controlled, phased migration of the existing book.
The firm adds that the Platform Transformation Programme “continues to make good progress.”
A further update will be provided with the company's full year results.
Paul Feeney, CEO, comments: “I am pleased that we have reached our soft launch phase which is an important milestone.
“The high quality delivery of this programme remains of utmost importance to us and we continue to prepare detailed migration plans to ensure customers and advisers remain well supported throughout the transition period.”
