We have just upgraded to Acumatica 2025R2, and we know Classic UI will be completely deprecated in 2026R2.
After checking with the community, we confirmed that for the same screen, all users must use either Classic UI or Modern UI uniformly; it is not supported to have some users on Modern UI and others on Classic UI for the same screen.
Our original plan was to roll out Modern UI gradually: let a small group of tech-savvy, quick-learning users adopt Modern UI first for testing, while all other users stay on Classic UI. Since this approach is not feasible, we would like to ask what is the best migration strategy?
Is the only viable option to switch screens one by one gradually ?
Our actual situation: many of our end users are older, slow to adapt to interface changes, and resist any layout adjustments. Even moving a single button’s position will lead to complaints from users. We need a smooth, low-resistance migration plan.
