Perform These Tasks
Before you upgrade your sensors to Cisco IPS 5.1(7)E1, make sure you have performed the following
tasks:
• Created a backup copy of your configuration.
• Saved the output of the show version command.
If you need to downgrade a service pack or signature update, you will know what versions you had,
and you can then apply the configuration you saved when you backed up your configuration.
Note You cannot use the downgrade command to downgrade from 5.1(7)E1 to 5.0 You can only
downgrade from new service packs and signature upgrades to the previous version of service
pack or signature upgrade.

Copying and Restoring the Configuration File Using a Remote Server
Note We recommend copying the current configuration file to a remote server before upgrading.
Use the copy [/erase] source_url destination_url keyword command to copy the configuration file to a
remote server. You can then restore the current configuration from the remote server. You are prompted
to back up the current configuration first.
Options
The following options apply:
• /erase—Erases the destination file before copying.
This keyword only applies to the current-config; the backup-config is always overwritten. If this
keyword is specified for destination current-config, the source configuration is applied to the system
default configuration. If it is not specified for the destination current-config, the source
configuration is merged with the current-config.
• source_url—The location of the source file to be copied. It can be a URL or keyword.
• destination_url—The location of the destination file to be copied. It can be a URL or a keyword.
