Reverting to the Previous License Key
You can revert to the previous license key if Metasploit Pro detects that a previous license key exists on the system. Use license key reversion to switch between different versions of Metasploit products. For example, if you install a trial version of a Metasploit product, use license key reversion to switch back to the full version.
Use the following steps to revert to the previous license key:
1.)
Select Administration > Software Licenses from the main menu.
2.)
If the system detects that there is a previous license key, you will see the Revert to Previous License area. Click Revert License. The License Details window appears after the system reverts to the previous license key.
