Re: How hard is it to move from on server to another?

A simple rsync should do the trick. How long will depend on how much data you have. I would just shut down the server, copy over the data directory and start the new server up. Should be a piece of cake. Keith David Ruggles wrote: I have a MySQL 5.x box and I am thinking about moving it

I have something to throw out. I just got done importing 140 million rows from a myisam table to a innodb table. While it worked I had a thought about 3/4ths of the way through. What if the transaction had been canceled about 130 million rows in? It would have taken weeks to roll back.
