You have built atop of Groovy/Grails? You do not get developers who want to maintain it? You want to get back onto the road of enough sized developer community in Java core? Or Java Spring or Spring-Boot? You have security issues, which are required to get fixed soon or even asap?

We have already migrated a set of Grails projects back to the default Java world either with core Java and JavaEE or with Spring/SpringBoot. Usually with REST api for the backend and a JavaScript UI like vue.js or Angular for the frontend.
Most clients come from Germany but also Austria and Switzerland. We are bilingual: German and English

If you want to know what we did, how we did and what the issues have  been, get in touch with us for a short 15-20 minute interview call. You can afterwards easy decide if you want to go on or not.
