IE 11 will be supported through Oct 13, 2026 through the ESU program [1]. Beyond this, no deadline is currently available for Cerner's support of IE11. Clients take, on average, 15-20 months for package updates. Assuming no special push is made, this means the average client should have Edge available in 2024 (not necessarily rid of IE11).
Since this is a larger, company effort, our SMART capabilities will continue to support this until that decision is made.
