I want to install Koha on my K12TLSP6 computer. In the process of installing I got to find out that Koha is not compatible with Mysql 5 but needs version 4.1.20. Is there a way of uninstalling Mysql 5 and running Mysql 4.1.20? yum remove mysql-server mysql takes care of uninstalling Mysql 5 but how to install Mysql 4.1.20?
