Hey @SASJR1 ,
Starting order of servers: First stop your Midtier, next Compute Tier and then Metadata server & Starting in the reverse order - https://go.documentation.sas.com/?cdcId=bicdc&cdcVersion=9.4&docsetId=bisag&docsetTarget=n1fxn02xr08732n1p0kph4z4145t.htm&locale=en For multi-tier environments there is also this: https://support.sas.com/kb/58/231.html
In order to install SAS 9.4 M7 you should contact your contact at SAS and request a SAS 9.4 M7 Software Depot and either do an upgrade in place or install in a new environment and migrate your content. Take a look at this thread (https://communities.sas.com/t5/Administration-and-Deployment/Upgrade-in-Place-Steps/td-p/444848) for documentation links and tips.
Kind regards
David
