Oracle has an interest of making profit. So they may interprete the licences more strictly than others. Do you deliver/install the MySQL Server. Is this the case you need a commercial licence (as long as your application isn't GPL). If the Server is beeing installed by your customers und you "only" use a existing installation then your customers may need a licence. (In this case olso the client dll must be excluded from your program) MariaDB is a fork of MySQL with a better licence. which can be used as replacement for the MySQL Server (with lesser risks for you and your customers.) A switch to and another DBMS like PosGres or FireBird ( which I also would prefer) may need adaptions in your program.

Oracle doesn't care if the software is only used internally. Better use MariaDB instead of MySQL. PostgreSQL is much more potent than MySQL.

Perhaps there are more relevant details on the call stack

Best by batchmoving the data from one db to another.

Cross platform isn't just mobile. The features could be usable on MacOS or Linux, too.

There is already a class for this: TInterfacedObject TEgon = class( TInterfacedObject, IHuman, IManager);

If XCode is fully installed, it should work. If they allow to install PAServer.

Using a virtualiszed OS from Apple is only allowed on Apple hardware.

The old server. The embedded (Server-)Client should be doing well.

They do. Only a small fraction of apps already got a arm version.
