“I just wanted to record my gratitude to the Vertali team for the exceptional work they have delivered over the last 18 months in preparing for the z/OS 3.1 upgrade, culminating in a seamless and completely incident-free deployment on Sunday morning. This was a major milestone for us and has further strengthened the trust and confidence I have in this team, who consistently work with us brilliantly and deliver outstanding results. Thank you all for your dedication, professionalism, and commitment.”

“Just wanted to personally thank the entire Vertali team for the excellent work and going way beyond your scope to assist our Application Teams. The success of the migration project would not have been possible without the expertise, extensive experience and knowledge demonstrated by the entire Vertali team, especially as the product was way beyond end-of-life support. A real pleasure working with Vertali!!”

I would like to tell you that I really enjoy working alongside Dave, Taz and Leinard. They are not just very good at what they do, they are also good people and I feel we have a great working relationship.

“Our project’s success has been nothing short of extraordinary. From the outset, we knew that the mainframe migration was our biggest and most consequential milestone on the roadmap. More than a month into production, we can confidently say that this migration has ran far smoother and more seamless than our last one. This impressive outcome is a direct result of the exceptional teamwork, creativity, relentless problem-solving, and unwavering ‘can-do’ attitude shown by Vertali’s team every single day since the beginning of this journey.”

“We’re delighted with the work of the Vertali team, and in particular Dave Stapleton. So much so that we’re exploring his eligibility for an internal award to recognise his contribution. As a major digital retailer, we depend on the smooth running of our mainframe operations and, recently, Vertali has tackled a Data Centre move and IBM z/OS V2.5 upgrade. Dave is hardworking and, importantly, is also transparent in his work. He keeps us fully informed, telling us what’s being done and what needs to be done.”
