Is it possible/hard to rename the Sitecore Databases after installation?

Our installation in our development environment was given a very confusing prefix for the databases.

Is it possible to rename them?

How much trouble am I getting myself into?

using: Sitecore 8.1 Update 3 and Coveo


  • If you are referring to the actual database names in sql server, you will change them in connectionstrings.config located in your site's app_config folder.
    These are different than the database names "master", "web", "core" which are IDs in your configuration files and are used to pick the connection string to use.
  • Just rename them in your SQL Management Studio an be sure to put the new name in the connectionStrings.config:

    <add name="core" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=NEW_NAME_core;Integrated Security=False;User ID=USERID;Password=PWD" />
