Restoring MySQL user accounts, databases and configuration from backed up /var/lib/mysql directory

[Michael Park]

Last night, I backed up my Ubuntu 10.10 box using the sbackup utility. The process ran with the default options, which backed up the /etc /home /usr /var directories to a separate partition on my machine.

After the backup completed successfully, I installed Ubuntu 11.04 over the existing Ubuntu 10.10 partition and installed the lamp-server meta package using tasksel:

$ sudo apt-get install tasksel
$ sudo tasksel install lamp-server

When prompted, I entered the same MySQL root password as used on Ubuntu 10.10.

What's the easiest way to restore the user accounts, databases and configuration from /media/backup/var/lib/mysql to the new installation?

Thank you.
