# Restoring original security certificates for Integration Service

During the Integration Service upgrade, the installer automatically takes a backup of the keystore, and keystore password files in the <installationDirectory\Agent\backup_security_<oldversion> locationAfter the upgrade is completed, these backed up files are automatically restored to the following directory location.

• (Microsoft Windows) <installationDirectory>\pw\pronto\conf
• (Solaris or Linux) <installationDirectory>/pw/pronto/conf

If the Integration Service upgrade fails, you may not be able to restore the automatically backed up security certificate files. For more information, see .
