I would start by finding out more about the data that you will be moving. Like What type of application this customer runs. when are they not getting hits. If they are always getting writes to the database then what time of day is slowest for them. Also if this is a heavily used web app expecting no downtime is quite a feat to ask for. But to move the database my suggestion would be to backup the database, restore it on the other server and then setup replication.

then I would point them to the new database so that all new writes will go to the new database while they are getting in between writes poplulated from the old db server.

course this is assuming that they are using
php , mysql , and apache like you said.
