Installing the CommServe Software using a Different SQL Instance Name

You can install the CommServe software using a different SQL Server instance name.

Before You Begin

If the data/configuration information of an existing CommServe component should be retained, these steps should be done first:

  • Back up the all user databases on the CommServe host
  • Uninstall all Commvault software products
  • Uninstall the existing SQL instance.


Use native SQL backup tools to create several backup copies of each user database and keep at least one copy in a secure place. Prior to installing the new SQL Server instance, create a registry value containing the new SQL Instance name. Use the following steps to configure the szUserSQLInstanceName registry key:

  1. Log on to the computer as an Administrator or as a member of the Administrator group.
  2. Click the Windows Start button and then click Run.
  3. Type regedit and then click OK to open the Registry Editor window.
  4. Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > GalaxyInstallerFlags . If the key does not exist, create it.
  5. Right click the GalaxyInstallerFlags key and select New > String Value.
  6. Specify the Value name as szUserSQLInstanceName.
  7. Double click szUserSQLInstanceName and in the Value data box, type the name of the SQL instance to use. Click OK.
  8. Close the Registry Editor window.
