/**
* Since version 2.15, we have merged the single-stream and HC detector workflows. Consequently, separate logic for profiling is no longer necessary.
*
* During a Blue/Green (B/G) deployment, if an old node communicates with a new node regarding an old model, we will not execute RCFPollingAction to
* determine model updates. However, we have fallback logic that checks for anomaly results. If any results are found, the initialization progress is
* set to 100%.
*
