data files. As long as you are not trying to "upgrade" from version 3.23 to
version 4.1, you are okay with copying the data files from one machine to
another.

Subject: Migrating Database
Greetings all,
We are migrating our web site from one server to another and are having some issues with transferring our MySQL database. Here's the process we're currently using:
1) run mysqldump for each table in our database (i.e. one file for each table)
2) compress each file using gzip
3) transfer the files to our new server
4) decompress
5) import each table using:
mysql [dbname] < [filename]
Here's the problem: several of our tables have over 20 million rows, and this import process is taking well over 6 hours. Obviously, our site cannot go live until the database is fully imported, and this is much too long for us to be down.
The two possible solutions I've researched are:
1) Copy data files directly. This concerns me because of possible version incompatibilities. 2) Using LOAD DATA commands. I'm not familiar with these at all, and frankly, not real sure how they work.
Can anyone offer us some advice as to the easiest way we can accomplish this, whether it's one of the above solutions, or another one completely?
Thanks in advance!
