Hi @shubhanshusi2 ,
When using the AEM Cloud Content Copy Tool to copy content from a higher environment to a lower environment, the tool does not automatically trigger asset reprocessing by default. The Cloud Content Copy Tool is primarily focused on copying content nodes and associated metadata.
Content replication tools, including the Content Copy Tool, typically aim to create an exact replica of the content in the destination environment. This means that the copied content, including assets and associated metadata, should be identical to the source.
If the Dynamic Media configurations differ between the source and destination environments, the behavior would depend on the specific implementation and configuration. In some cases, the copied content may retain the original Dynamic Media configurations from the source environment. In other cases, the Dynamic Media configurations may need to be manually adjusted or synchronized in the destination environment.
