# Backup the current Service Pack

Older service packs are not available for download from our website. If you do not have a copy of the service pack that is currently installed at the restaurant you are about to upgrade, you can get it within the Maitre’D file system:

1- Browse the **C:\ drive to C:\POSERA\MaitreD\PRG\Setup.**

2- Within the Setup folder, you will find a file called **MD7BOSP.ex**e. This is the service pack file that is currently installed. Copy that file to a removable media for safekeeping, in case a rollback is needed late.
