Hello

what do you mean by "databases that are expired for more than 3 months" ?

Should we put the same subscription code on the staging instance than the one on the production instance ?

regards

Maurice

Hi, 

As per Odoo.sh FAQ:

The platform will automatically lock databases that are expired for more than 3 months. If this was a staging or development build, simply use the "Rebuild" button on the Builds page to have a new one. If you need to salvage the expired database you can still download its dump. If it's a production database, you can start over by drag and dropping the production branch to development and back to production to make a fresh start, or you can contact us if you need it unblocked.
