Upgrade From MySQL 5.7 to 8.20 (1 reply)

I am trying to upgrade from MYSQL server 5.7 to 8.20. I need to increase the innodb_buffer_pool_size to 8G (Default is 8M). Here are the steps I followed:

1. Uninstall MYSql server 5.7
2. Install MYSQL server 8.20.
3. Change the innodb_buffer_pool_size in my.ini file from 8M to 8G.

Result: The server is stopped and cannot be started.

Please help resolve the issue. Thank you for your kind attention.
