Accidental change of version from 5 to 8

[david Ce]

Hi,

I had a Docker container running MySQL 5, but I deleted both the container and the image. When I recreated it using the latest image, it installed MySQL 8. After starting it, it didn't work properly, and MySQL deleted the .frm files. Now, I only have the .ibd files left.

I tried recreating the structure to recover the .frm files and then replaced the .ibd files with the old ones, but it didn't work—0 records were recovered.

I’ve now set up a new MySQL 5 container, but unfortunately, I don’t have a backup.

Any suggestions on how to recover the data?

Thanks!
