Hi Nitin, I have tried once, migrating from windows to Koha. You can backup your Database using either mysql command or Mysql Administrator if you are not familiar using command line. mysql Administrator is pretty easy. You can download it from mysql.com. You can follow the following step: 1. Check your Koha version. eg: 2.2.4. So, you need to install 2.2.4 version first on Linux. 2. Install Koha on Linux.Make sure it is running well. 3. Backup your Koha database in Windows. it will generate sql script. 4. Restore database (run this script) in Linux. 5. Map database which Koha would read to your new database. You can do this inside /etc/koha.conf After that, if it is work well, you can run upgrade script to upgrade to a newer version (eg: 2.2.5). Hope it can help.

I have now successfully installed Koha on Linux and would like to use the same database. I tried copying the database folder onto the linux database folder, but it doesnt seem to work. How do I use my earlier data? Maddy
