Re: Upgrad 3.23 to 5.7

[Frederic Descamps]

Hello,

We are talking a software that was released almost 22 year ago.

What I would suggest is to dump the data using mysqldump, I would first try with the one installed on the system.

Then load it to the new MySQL 5.7 server: see https://web.archive.org/web/20010127191700/http://mysql.com/doc/m/y/mysqldump.html

After that I also suggest you several steps:
- modify your tables from myisam to innodb storage engine
- upgrade to 8.0 to avoid running again on a old version.

good luck.
