We have already seen Koha LIS Installation in our last Post which is available @ https://abhishek.nagar.me/koha/install the same steps can be used to install the Latest Version of Koha i.e 24.11 which was released in November 2024

I am very well sure that you might be also a lazy chap like me and would be not upgraded your Koha Installation at a regular basis still i presume that you must be using at least Koha 20.05 if yes use the following procedure to upgrade/migrate your current Koha Instance to Koha 24.11

Assumption : Koha Instance Name is library, Database Name is koha_library

Step 1 ) Install Koha 24.11 using the Procedure mentioned in our earlier blog post. and yes i recommend new Installation over Upgrade as by new installation you get a easy and safe opportunity to upgrade your Base OS to Debian 12 

Step 2) Take Backup of Database from Old System

• Open Terminal on the Old System and execute the following to take backup
• sudo mysqldump --single-transaction -u root -p koha_library > koha.sql

Step 3 ) Move the Backup file koha.sql generated in Step 2 to new/upgraded system using scp or any backup device whatever you are comfertable with.

Step 4 ) Restore mysql Backup to the New System

• Open Terminal on the New System and remove the Existing Database which is currently already empty
  • sudo mysql -uroot -p
  • drop database koha_library;
  • create database koha_library;
  • exit;
• On Terminal  execute the following to restore backup (this will take time depending on the backup size)
  • mysql -uroot -p koha_library < koha.sql 
  • exit
• On Terminal Upgrade Database Schema
  • sudo koha-upgrade-schema library
• On Terminal rebuild the Zebra Index
  • sudo koha-rebuild-zebra -v -f library

Wohla !!! you have upgraded Koha to 24.11 :) Enjoy Open the Staff Interface with your Old Credentials as they are now migrated :)
