Description:
Note: MySql 5.6 service is currently running as a windows service.
Also note: MySql was installed with minimal alterations to the configuration.
About the only change (of significance) was to the 'datadir'.

I Tried upgrading to the latest MySql community server, but can't get past "check and upgrade database" step.

I gave the correct root password, but clicking 'check' it hangs for a while and then tells me "MySql server is not running, connection cannot be established" (even though windows services show that MySql is running, and I can log into it ok using workbench)

How to repeat:
install mysql 5.6.12 (I think this was the original version)
then upgrade to the latest version of mysql

Suggested fix:
I suspect your testing phase is a bit slack.
Perhaps you could invest more time into debugging your product

Thank you for the bug report. Please check the Manual about steps (5.6->5.7->8.0) when upgrading from minor version like 5.6 to latest version like 8.0. I quoted the Manual text below: 

https://dev.mysql.com/doc/refman/8.0/en/upgrade-paths.html

Upgrade that skips versions is not supported. For example, upgrading directly from MySQL 5.6 to 8.0 is not supported.
