We are extremely satisfied with the reliability and robustness of Cisco Prime Infrastructure, which we have been using for many years. Compared to newer products such as DNS centers or others, it has proven to be much more stable, which is important for large-scale operations. Stability is a primary concern for us, and we are glad that Cisco Prime Infrastructure meets our expectations in that regard. Furthermore, in regards to Legacy Plus new hardware, Cisco Prime has proven to be a reliable and adaptable solution thus far. Not only can it support older hardware, but it also has the capability to handle new features with the latest updates. If we consider new solutions such as DNS Center, we may have to sacrifice some legacy features that we still rely on. We may need to continue using these legacy features for a few more years due to various reasons such as budget constraints or the site not being a high priority. However, if we switch to a new product at this stage, we may lose a lot of the monitoring and other capabilities that we have with Cisco Prime. We have a close relationship with Cisco and understand that they are not prioritizing investments in Cisco Prime as they are encouraging customers to adopt the Cisco DNA Center. This means that we don't anticipate many new features to be added to the product in the future. While we know that we will eventually have to transition to a new solution, in the meantime, we plan to do a quick refresh of our legacy products.
