[wildfly-dev] Any guidelines on dealing with (duplicate) tests in legacy-ejb-client testsuite?

I was working on a change and a testcase related to one of the JIRAs open in WFLY and happened to notice that we now have a testsuite/integration/legacy-ejb-client module. It looks like this module has testcases that are also part of testsuite/integration/basic - i.e. copy pasted. So we now have 2 copies of a testcase for example EJBClientAPIUsageTestCase. What's the guideline when dealing with these testcases? Should both these testcases be kept up-to-date with any changes to the behaviour of the server interaction with the remote client? The context of my question is this PR https://github.com/wildfly/wildfly/pull/10466 -Jaikiran
