Re: Unsupported redo log format

I did that, and it got around the problem with the log files. However, now I get:

2020-02-24T01:50:58.152010Z 1 [ERROR] [MY-013168] [InnoDB] Cannot upgrade server earlier than 5.7 to 8.0

I know - I probably should have read the manual. In my defense, I just had the server install mysql, and I didn't know there was a version issue.

I'd happily just install version mysql 5.6 or 5.7 and call it a day - do you know how I'd do this for Centos 8?

Alternately, is there a way to massage the existing files so they'll get along with mysql 8?

Thanks again.
