Description:
Hi,

On our DEV environnment, we performed an upgrade from Mysql 5.7.19 to 8.0.11.
We installed the packages using 'yum', made all necessary checks provided in the 'upgrade' documentation.

But, we can't start the service, here is the error we have (using --log_error_verbosity=3) on the 'Data dictionnary initialization' (see the error_log_file.txt).

Attaching also our 'my.cnf' file.

Any way we can fix this one ?

Thanks for you help,
Francois

How to repeat:
- Stop Mysql 5.7.19 service
- Upgrade Mysql Server to 8.0.11 using 'yum'
- Restart the service

Hi,

You had to fist upgrade to the latest 5.7 before you were upgrading to latest 8.0 as documented https://dev.mysql.com/doc/refman/8.0/en/upgrade-paths.html

Thanks
