Complex tariff and upgrade Solidres 4.6.0

Hello everyone,

Will updating to the latest version of Solidres (4.6.0) delete or alter the settings for "Complex Tariff"?
I ask because I see that this plugin has been discontinued.

My client has imported a JSON file into the room settings to configure seasonal rates.

I am concerned that everything might be deleted or rendered non-functional—especially since bookings for the winter ski season have already begun, and it is crucial that everything works perfectly right now.
If the new "Rate Plan" plugin automatically retrieves all the existing settings from the database, then that would be ideal. Could you please confirm if this is the case?

Thank you in advance for your response.

Best regards,
