I have a (Virtualized/Hyper-V) MySQL 8 (22.214.171.124) DB server whose installation has become corrupt and will no longer start the service, or report any errors as to why it won't start (this is a virtual Windows 2008R2 server).
So I went and created a brand-new, duplicate, VM from scratch, installed (the same version of) MySQL on it, and am now trying to figure out how to get the tables from the old server into the new one.
If I simply copy the entire Data folder over, as is the process described in virtually every article I've found on the subject, the new instance also won't start (exactly like the old one won't) but if I then copy a pristine MySQL.ibd file (from the clean installation) into the migrated Data folder, the service will, once-again, start normally, but none of the copied Databases/Tables will exist in it.
All I want/need to do is get the shiny, new, clean, MySQL to see and incorporate all of the old databases from their original files, but after more than a day of reading many guides on how to do this (from here and elsewhere), I have not been able to find a solution that works.
So here I am, asking again, in 2020, for MySQL 8(.0.16.0), on Windows 2008R2, what exactly do I need to do in order to fully recover these tables into a new server when some elements of the base structure are corrupt/invalid?
