# Activate dynamic update packages

To introduce the changes from an imported dynamic update package into your SMC, activate the dynamic update package in the SMC Client.

##

Note: The Management Server verifies the digital signature of the dynamic update package before activating it. The signature must be valid for the activation to succeed. If the verification fails, an error message is shown. Verification failure can result from an out-of-date SMC version or an invalid or missing signature.
