Minor upgrading is a common task in Alfresco. In many cases, upgrading just only WAR artifacts should enough to complete the process. However, what about the patches applied in other resources like configuration files?
Following a customized process to upgrade from 5.1.e (201602) to 5.1.f (201604) is described. This process can be take as an example for any other minor upgrading between different Alfresco versions.

We can see that, in addition to WAR artifacts (alfresco, share, ROOT and solr4), some other components have changed. Binary components (alfresco-share-services.amp and alfresco-mmt.jar) can be overwrited, but let’s examine other changes in order to decide how they apply to our Alfresco installation.

This simple process allow to identify and to apply all patches introduced by the new minor version. However, depending on your initial system, this steps can be slightly different. Please, ask an expert if you are doubting after reading a blog post like this before going hands on.
