Also extract your MySQL tables. There may be differences in the format of the
data storage between versions. If your new installation is unable to read the
binary files from the old version, and you no longer have an old installation to
read those files, you will be in trouble. You can use mysqldump to extract the
contents into text SQL format. This can be used to re-create all the tables on
the new installation if the new MySQL cannot read the binary versions.

Read whatever MySQL migration documentation you can find on the web.
