Sysadmin Transfer database to a new server using a Master to Master or a Master to Slave?

Hello

---

Do you recommend me to use for the database transfer a Master to Master setup and when is done to stop Mariadb from the old server and start using the new one or a Master to Slave setup and then stop the Master from the old server and change the configuration to the new server and start it?

Thank you

 

Transfer from one server to another and avoid the time needed to import the database in .sql file format that will take much time...

 

I prefer mysql replication but i am not sure if it is better to do a master / master or a master / slave
