Moving / Migrating Microsoft SharePoint Server Databases from one server to another might be difficult as you need to reconfigure all the related DB(s) to point at the new server. This might be acceptable if we are talking about the SharePoint Content Databases, but how about the below scenarios:
Scenario # 1:
Moving the SharePoint Configuration DB(s) or the SharePoint Service Application DB(s)?
Scenario # 2:
Lets consider another scenario, where you want to move the SharePoint DB(s) from a Single Standalone SQL Server to a Highly Available Cluster Server, or maybe even configure it to use on of the new features such as SQL Server AlwaysOn.
The answer to the above scenarios might not be as straight forward as it seems, as you might need to reconfigure each DB & Service Separately, so how about suggesting the use of SQL Server Aliases as it could be consider a good starting point for both of the above scenario.
To start take a backup of the SharePoint Server DB(s) that you want to move, this can be easily done using Microsoft SQL Server Management Studio. After the backup is complete restore the Database(s) on the new server.
After successfully restoring the SharePoint DB(s) we need to start configuring the SQL Server Alias. To achieve this goal we need to do the following steps on All the SharePoint Servers in the Farm; such as WFE, APPS ...etc.:
Go to Start >> Run >> Type CliConfg.exe and the below screen will appear:
Select the Alias Tab and click Add:
Select TCP/IP from the Network Libraries and Enter the following Values:
Server Alias: This is the Old SQL Server Network Name
Server Name: This is the New SQL Server Name Network Name
Port Number (if needed)
And that's its, you will see the new SQL Server Alias added as shown and you are ready to start using the new Database.
Don't forget to apply these changes to all the SharePoint Servers in the farm. hope you found it useful
Below are some useful references that provides more information about the items mentioned in the above post:

Create SQL Server Alias – CliConfg.exe
YOU HAVE THE SERVER NAME AND ALIAS VALUES BACKWARDS!
Server Alias: This is the New SQL Server Name Network Name NO THIS IS THE OLD SERVER
Server Name: This is the Old SQL Server Network Name NOT!!! THIS IS THE NEW SERVER NAME.
I think JohnnyJM is right. OP got it reversed.
i think he got it correctly. i havent tested it though but I think if you run the CliConfg.exe on the destination/New server, it would make sense that it would be the Alias and server name would be source/Old server
I tried the cliconfg.exe while moved the SharePoint database to another server
Server Alias : Old Server Name [The server were having database ]
Server Name : New Server Name [New server with moved database]
You are absolutely correct ...
