Well it depends on what componenets critically being used there B2B IS or ES.

Start with B2B4.x (IS,TN) and second with ES (use Enterprise Upgrade Utility as told in previous thread)
IS/TN Server with JDBCPools configuration for Database
Broker Server(BrokerAdmin)
Add-on components (EDI,Adapters…)

HTH,
