RedHat Build of OpenJDK can run oracle Solaris servers ?

We hava a java application that runs on java 1.8. now we want to migrate the application from oracle jdk to open jdk. Currently we support Solaris and RedHat OS. We want to move the application to open JDK since our majority of users are using REHL and Redhat provide free support for rehl subscription users. But we want to support open JDK for solaris users as well. Can we still use same REHL open jdk on solaris. do solaris customers need to get subscription to use ?
