Hi devsharepr1ff5,
Thank you for reaching out to us.
Any integration tile being shown in 'available for upgrade' section means the integration needs to be enabled for the given MBI Customer. While most of them are chargeable, Google Analytics is free.
The prompt you mentioned in your query is a way to notify MBI Support teams that you would like to enable the given integration.
This will not replace/disturb any existing GA3 (Universal Analytics) integrations.
Just to let you know, we will release the GA4 integration soon. We will keep you informed about it.
Regards,
Adobe Commerce Intelligence Team
