In this short post we will see how to change site code of Configuration Manager client. Every site has a site server, a site database, and a three-character alphanumeric site code. The site code must be unique in the hierarchy. Site codes are used to identify the sites in a Configuration Manager and site code must uniquely identify each Configuration Manager site in the hierarchy. Having said that there might be reasons why you want to change the site code of the configuration manager client. Let’s assume you have ConfigMgr 2007 installed in your company and now you want to migrate the objects to Configuration manager 2012. ConfigMgr 2007 and System Center 2012 Configuration Manager publish information into the same Active Directory system folder when implemented in the same domain. As a part of the migration process, you should plan for new site codes for your System Center 2012 Configuration Manager hierarchy.
When you are choosing the site code while installing SCCM you should keep few things in mind.
1) Avoid using reserved names such as AUX, CON, NUL, PRN when choosing site codes. Click this link to see list of reserved file names.
2) Avoid reusing site codes previously used in your ConfigMgr hierarchy. Configuration Manager Setup does not verify that the site code entered is not already in use. Site codes are stored in the site databases. If you were to reuse a site code, you may discover that all references to the old site were not fully removed or are re-introduced from a restored backup. This could cause problems resolving the site.
