How to do Mysql migration from 5.0 (320bit windows) to 5.6 (64 bit windows)?
You use mysqldump.

Step 1. Dump your original 32 bit database. mysqldump my32bitdb [options...] > mydb.sql

Step 2. Copy the file mydb.sql to your new server

Step 3. Load the 32 bit database mysql -u root -p my64bitdb &lt; C:\path\to\mydb.sql

With 10GB of data, it shouldn't take much more than ~ 1hr.
