Please note that there is RHEL compatible packages of Squid-3.0 available. See "Download -> Binary distributions". Migration is 0. Make a backup copy of squid.conf 1. Install new version. (rpm -U if using the binary rpm) 2. Update squid.conf so it works with new version. See release-notes for some guidance on what needs changing. "squid -k parse" will also tell you. 3, Start new version. Rollback is 1. Uninstall 3.0 2. Reinstall 2.6 3. Restore the old squid.conf 4. Start 2.6 Regards Henrik
