Can I open a mysql 5.1 database from mysql 5.5? - mysql

I have a MySQL 5.1 database (The data files in F:\ProgramData\MySQL\MySQL Server 5.1), but I'd like to open the database from MySQL 5.5 on my new computer. I don't have MySQL 5.1 running any longer because my old computer's motherboard failed, and all I have is the hard drive where my 5.1 database resides.
Is there a way to open the old MySQL 5.1 database from MySQL 5.5?
I should add that my database is InnoDB (I think). I had another database that was MyISAM and I was able to open it in MySQL 5.5 just by copying the old database directory over to the new MySQL data directory.

In the Linux world you can simply copy the file system /var/lib/mysql/[yourdbfolder] into the new file system. You then have to run mysqlcheck --repair but all should be good after that.

mysql workbench dropped table

my MySQL workbench setup with a database on it. I was using xampp with it but xampp stopped working so I uninstalled and reinstalled it. could this be the issue as to why the table went missing?
workbench is only a Gui, it will not drop anything without any user input.
MySQL server and xammp would work parallel when you choose a different port for one of them.
Your problem is that both save theier files in diffrent path(default)
MYSQL saves its data in
C:\ProgramData\MySQL\MySQL Server 8.0\Data
While xammp stores their database in
C:/xampp/mysql/data

Your question is not clear. However, you can:

Dump your database to a sql file
Switch to MySQL 8
Restore from the dumped sql file
Note: If you have no purpose to upgrade, you should go with MySQL 5.7

How to move MySQL 5.6 server data to another one not depending on dump command?

I installed Windows 10 yesterday and couldn't back up my MySQL database with admin commands. But Windows 10 installation didn't remove the old files. So I can access the old MySQL server directory with those files. Is there any way to move data moving files to the new MySQL's directories?
For more information, I am using MySQL 5.7 server and the previous version was 5.6. But If there is a way, I can downgrade the new version to 5.6.

Mysql how to backup and restore after version 5.5

The mySQL manual says that backup and restore are deprecated, and removed in version 5.5.
I have ISAM tables dumped with "backup" from an earlier version (5.0) - how can I restore these to a 5.5+ mySQL database.
I would copy the *.MYD and *.frm files into the target database directory, and then run a REPAIR TABLE on each table (so as to rebuild the indexes).
The "target database directory" is datadir/dbname where datadir is a server parameter, and dbname is your target database name.
datadir is found with the SQL command SHOW VARIABLES LIKE 'datadir';.
I dont mean to sound snarky, but older versions of mysql can be obtained. Why not install a copy of the older version of mysql, export to SQL using mysqldump, then reimport into a newer version.
Perhaps use a virtual machine inside Virtualbox.
