How to syncronize two online databases

I can outline the steps to synchronize two databases online?, after analyzing the databases are differences and not activated the option to apply changes.
thank you very much
I beg showing all steps to synchronize the two databases properly

Please just keep in mind that the dialog "Synchronize database" is not yet finished. Until now I avoided to dive into the remaining, most complicated coding stuff there..

In all the time has it foreseen to finish the programming of the option to synchronize the databases?
To have both synchronized databases, can I use the option import - export at the moment?

Yes, of course the synchronization dialog should be finished at some point. Otherwise I would have killed it already. It's just so complex, like a science. So it's a thing you do not implement somewhere between normal work and bringing two kids to bed.

There is no option "import - export". You can use the "Export database" dialog to create a dump file, and import that .sql file afterwards in the target database.
