Upgrading to SQL Server 2014 SP3 _ Clarifications help needed We have SQL Server 2014 SP2 GDR with below:


Availability Groups 
TDE enabled for structured data
EFS enabled for unstructured data


Now the DBs are with AOAGs and encrypted ,  I am planning to upgrade current SQL Server 2014 SP2 GDR to SQL Server 2014 SP3. Can anyone help me with any issues / pre-requisites or anything that can happen adversely.

Though I am planning first upgrade DEVELOPMENT / STAGING , please share your thoughts as I need to upgrade my PROD . I am little worried as the DBs are with TDE + EFS . Does encryption has any linkage with SP3 upgrade.
As far as I know, Service Packs on same major version ( 2014 ) does not have any impacts on these features.
