If a user upgrades the plugin from the free version to the pro version, he has to download and install the pro version manually. The pro version won’t be installed automatically.

Instructions:

• Download the Pro version from My Account→ Dashboard→ Downloads.
• Install the Pro version as usual.
• Deactivate and delete the free version.
• No data will be lost. All the previous sliders and shortcodes will be carried to the pro version.
