Moving all of the databases from one server to another

Log in as an admin on MySQL Console and lock the database to allow only read operations.

mysql> flush tables with read lock;
mysql> set global read_only = on;
mysql> exit

Dump all of the databases into a file.

$ mysqldump --lock-all-tables -u root -p --all-databases > dbs.sql

Copy the dump to the new server. RSYNC is preferred over SCP, especially if the file is large.

$ rsync -tvz --progress dbs.sql
$ scp dbs.sql

The DB can be (optionally) unlocked. This may or may not be a good thing to do in your case. Do it at your own risk.

mysql> set global read_only = off;
mysql> unlock tables;
mysql> exit

On the new server, execute this command to import the new dumped SQL file.

$ mysql -u root -p < ~/files/dbs.sql
