Does anyone have the steps to be followed for upgrading from Pega 8.4.0 to 8.4.1. The software downloaded is around 3.4 GB. Is applying the latest patch release version same as "upgrade". Because in the "deployment guide" section, i see two PDF's. One says is an installation guide and the other is referred to "Upgrade guide". The upgrade guide talks about upgrading from all versions including from 7.3 onwards.
I am not sure which steps should i be following as i am just upgrading from Pega 8.4.0 to 8.4.1. I would assume the upgrade for this should be much simpler..
