Merging

Both databases that you intend to merge must be on the same account.
In cPanel

1. Click phpMyAdmin.
2. Click "SQL" at the top.
3. Underneath "Run SQL query/queries on server "localhost"", insert this code: "INSERT INTO DB1.TABLE1 SELECT * FROM DB2.TABLE1". Replace DB1 and DB2 with your database names, and TABLE1 with the name of the table you are trying to merge.
4. Click "Go".

SSH/Shell

1. From SSH, type the command to access mysql, "mysql -u MYNAME -pPASS", replacing MYNAME and PASS with your username and password.
2. Now enter this command, again replacing DB1, DB2, and TABLE1 with the names of your databases and the table you wish you merge. "INSERT INTO DB1.TABLE1 SELECT * FROM DB2.TABLE1;"
3. repeat for any other tables you wish to merge.

Note: If you wish to have the data in DB2 overwrite the data in DB1 and they share a primary/unique key, use "REPLACE INTO" rather than "INSERT INTO"

2. Click "export", at the top.
3. Select "Save as file" and click "Go". An .sql file will be downloaded to your computer.
