Support for WLM metrics in RMF was introduced at v2.4, therefore we do not recommend you to copy a checkpoint that includes these metrics to an LPAR that has an older version of RMF (or an older version of DCE). If you copy a checkpoint that includes these metrics to an LPAR with an older version of RMF, where both LPARs have at least DCE1157 installed, then the metrics will be sent to Splunk but the values will be null.
If you want to reinstate an older version of DCE on an LPAR, or copy a checkpoint to another LPAR that has an older version for DCE or RMF, ensure the checkpoint does not include WLM metrics.
