Move server cluster roles to inactive node

Hello, I want to fire a script/one liner prior to patching a cluster node. I want posh to detect if its the active node. If so, move the roles, services, etc to the inactive/standby node.

As a result I can have my patch management application proceed to install/reboot, etc.

I found a few resource but it seems to do much more than I really need.

Any advise on how I can get started?

So far I have collected this but I am not sure how to further tweak it to dynamically move to the inactive node.                       

$TargetNode = Get-ClusterNode -cluster 'MYCLUSTERNAME' | ? {$_.State -eq 'Up' -and $_.Name -ne $CurrentNode}     

Thank you.
