Good afternoon. I study Odoo for my clients to give them recommendations for implementation. I read in the documentation that it is possible to switch from Odoo Online to On-Premise. I created an On Line database, saved a duplicate to my computer and tried to download On-Premise through the manager. I was able to load the database using Restore Database, but I got an error "This database may not be compatible" and when I try to run it says: "Wrong login/password".

Please tell me how can I connect the online database to On-Premise on localhost
