Disable Membership Pro

We have an active Membership Pro installation and need to clone the entire site to a subdomain and test major changes and upgrades. I would like to completely disable Membership Pro in the cloned site so that no renewals or reminders are sent out as this would cause duplications. 

How do I best achieve this?

Thanks

Hi Jeff

Just disable System - Membership Pro Reminder plugin and no reminder email will be sent.

If you want to prevent users from accessing to Membership Pro on the old site, maybe disable the component or maybe take the site offline during the migration process
