If we currently have 5 heavy forwarders sending logs to a single indexer, how can we centrally forward all raw logs to another SIEM/Log management solution?

Dear Experts, We have a Distributed environment using around 5 heavy forwarders across various locations sending logs to a central indexer. Now we have a requirement to forward the raw logs to another log management/SIEM solution. What do you guys recommend to forward the logs? We are looking for a way to centrally forwarding the logs, Thanks in advance !
