Hi,
I am from Spain, excuse me my bad English
I have a SQL 2014 Enterprise in production mounted with multiple instances on a Windows 2012 r2. This SQL is in stand-alone mode without any HA or FT
This installation made someone before I arrived and now they ask me to provide high availability to SQL, for example, if I want update the OS can restart a node while another has the operational BD
Is it possible at this point that I add to my SQL HA installation?
Can the SQL being in production, adding another SQL server and provide HA?
Thanks in advantage
