Found several articles on side by side upgrade of sqlserver. Can I use the same server to install sqlserver 2014 or do I have a install on a separate server? If someone has a complete document that they followed to upgrade will be very helpful since upgrade process is in separate sites.
Also if I have more than one instance, they has to named different? Will I have two services running and have to delete the old service.
I also have several Linked Servers, Integration packages to move.
