Import old data to new Mysql database

[samuel]

Hi,

My machine was down before, fortunately I have back up the whole
/usr/local/mysql directory. Now I have setup a new mysql on a new
machine, how can I import the old data back to the new database??

My old mysql version: mysql-3.22.32
new mysql version: mysql-max-4.0.3-beta-sun-solaris2.7.sparc

I used to run the mysql like this:

/usr/local/mysql/bin/mysql abc

should I add the user abc to my new database first? and how?

Thank you for your help!!
