Answer 1

It is possible, I found out a solution:

1. Install new xampp
2. Copy your old database folder from xampp\mysql\data\databasefolder to Paste in your running xampp folder
   C:\xampp\mysql\data
3. After that stop mysql and apache service then backup your running xampp files ib_logfile0,ib_logfile1 and ibdata1 and store in safe place
4. Then Copy same file (ib_logfile0,ib_logfile1 and ibdata1) from old xampp\mysql\data\ and paste in your running xampp server C:\xampp\mysql\data\
5. Start mysql and apache service Open CMD Fire command C:\xampp\mysql\bin>mysqldump -u dbusername -p dbpassword dbname>D:\exportdb.sql
6. stop mysql and apache service and restore your main ib_logfile0,ib_logfile1 and ibdata1 file (check Step 3)
7. after than again start service and open http://localhost/phpmyadmin/ and import database backup from D:\exportdb.sql Now your backup is working :)

I just copied the data folder from the mysql folder inside the xampp folder structure and paste it in the same structure in my new installation, Everything is working fine now.

Answer 3

1. Copy your all old databases from old to newly installed Xampp under this dir

C:\xampp\mysql\data\

2. Copy these below files from new xampp (C:\xampp\mysql\data) and keep back up

ib_logfile0, ib_logfile1 and ibdata1

3. Similarly copy and replace ib_logfile0, ib_logfile1 and ibdata1 from old xampp to new xampp

4. If previous Db has crushed or error like mysqld.exe has stopped working use below 2 lines inside my.ini file of mysql

   [mysqld]

innodb_force_recovery = 2

innodb_file_per_table=1

5. Restart Apache and MYSQL and go to PHPMyadmin to export your previous database.
6. finally replace your back up ib_logfile0, ib_logfile1 and ibdata1 that was taken bakup previously

Answer 4

I ran into the same problem. I had all my projects in mysql which I lost somehow.

mysql under my old xampp had got deleted/uninstalled somehow. I did not even have the data folder to copy to new xampp location.

I browsed through the folders and found mysql/data and mysql/backup in below location.

C:\xampp\perl\mysql\data

C:\xampp\perl\mysql\backup

This is what I did.

I copied both these folders in place of new xampp mysql/data and mysql/backup folders.

I also copied other files (not folders) under /mysql from old xampp to new xampp /mysql.

Stop new xampp mysql and apache servers if running. Restart.

Viola I got all the lost databases back.

Hope this helps.

Answer 5

Here's how I dealt with this kind of situation:

1. Stop the Apache and MySql services from xampp control panel.
   
2. Back up (just in case), then delete the data folder from your new xampp installation folder <physical_drive>/xampp/mysql.

   (The data folder contains the schema/table definitions (.frm files) for your tables.)
   

3. Copy the data folder from your previous xampp folder (or the backup) under mysql and paste it to the new location (i.e. <physical_drive>/xampp/mysql).
4. Now start the Apache and MySql services from the xampp control panel.
   

There you go, the tables should show up with their structures as you click on them.

Note: Make sure you leave the bin folder under your xampp installation folder untouched.

Answer 6

Set datadir = "D:\xampp\mysql\data" in xampp/mysql/bin/my.ini
