What is best practice for migrating? Should I us the wizard and on install have it update the exiting SQL or should I install a new instance and then migrate each database individually?
If I make a second install and have them run side by side until all databases are moved is there a way to switch which database instance is the default instance. Up till now the data source connection was simply the server name, if I install a second the connection is now servername\instance name. Not that this is a huge deal but I prefer the simple server name. I have looked at the alias but I have been unable to get it to work. I look at the new instance, TCP/IP is listening all. I open the alias and enter the dynamic port, the server name and the alias name but when I try to connect using the alias it can not find the instance.
I am working on our test server now and have not progress very far so if it is better to do an in place upgrade I could uninstall SQL 2014 and then run the install again.
