Client does not support authentication protocol requested by server; consider upgrading MySQL client

Then you will need to do the following:

1. Start DOS mysql script manager with command (I assume that you put MySQL/bin to the PATH enviroment variable):
   mysql -u [dbusername] -p, where dbusername is username for your database
2. Enter your current password and you will get mysql > prompt
3. Type:
   SET PASSWORD = OLD_PASSWORD(‘MyPassword’);
4. Type:
   FLUSH PRIVILEGES;

And thats it!

So, first you need to create dump of your existing database, to export it to a file. Here is the command:

mysqldump -P 3306 -u database_username -p database_name > /home/somedirectory/your_database.sql

-P - means port, if you don’y mention it default port is used (usually 3306)
-u – means database username
-p – means password but we didn’t specified it so after this command is executed we will be asked to type a password
database_name – is the name of your database you want to export
> location – at the end you specify directory where you want to create this dump

You probably want to zip this and you can use TAR (install Cygwin if working on Windows):
Here is the command:

tar cvf database.tar /home/somedirectory/your_database.sql

Transfer this file on other server using FTP… And unzip it if you want using command:

tar -xvf database.tar

Then import the database:

mysql -P 3306 -u  database_username -p new_existing_database_name < /home/somedirectory/public_ftp/your_database.sql

-P - means port, if you don’y mention it default port is used (usually 3306)
-u – means database username
-p – means password but we didn’t specified it so after this command is executed we will be asked to type a password
new_existing_database_name – is the name of your existing database on new server where you want to import data
< location – at the end you specify from which directory you want to import database

And thats it…
