Import Metricbeat (6.4) dashboard into Kibana 5.6 without direct connection

Elastic Stack Beats

Hi ,
I run metricbeat 6.4 on different nodes and send the date to one only redis server through a firewall.
Afterward these data are sent to ES 5.X via Logstash.
I would like to use the metricbeat dashboard for docker in my Kibana but

Metricbeat is in 6.4 and Kibana 5.6 !
Metricbeat is not able to join directly Kibana (firewall).

Thank you for your help .
Eric

I am not sure that will even work, there are changes between the versions, including new visualisations in later versions.

I'd like to be sure it's not possible.
I'm looking for a matrix compatibility between metricbeat and kibana about this dashboard
