You can use the dynamic CDT in a sysplex environment where some systems are not using the dynamic CDT.

When RACF is enabled for sysplex communications, RACF propagates the commands listed above to the members of the data-sharing group even when the command fails on the system where it was issued. If the command fails on any of the member systems, RACF does not back out or undo the command execution from the member systems where the command did not fail. This allows you to use the dynamic CDT in a sysplex environment where some systems are downlevel or are not using the dynamic CDT.

When you move a static class to the dynamic CDT in a sysplex environment and the static class is defined with different options on various systems, you will receive different warning messages on each system. Examine the message log on each peer system when you execute the SETROPTS RACLIST(CDT) REFRESH command to ensure that each execution completed as expected.
