Does this change impact on the JVM configuration (in this article)? (We may need to replace -XX:PermSize, -XX:MaxPermSize by -XX:MetaspaceSize, -XX:MaxMetaspaceSize. Anything else to consider?) We had done H/W sizing. The sizing sheet doesn't require to input JDK version. Is that mean this change is not impact on memory estimates in H/W sizing?
