Hello I have an hosting system based on a debian 3.1 with a mysql db v 4.0.24 I want to update that version to v5 (using apt repositories with testing version software, actualli installed with stable) my question is... When I change the apt sources config to get testing versions and run apt-get upgrade, what will happend with the ISPConfig data Stored in Mysql? Will the update maintain my data and connections will be able to stablish from ISPConfig to new DB without problems? Thanks P.S. ¿Will be any problem for using testing versions with ISPConfig?
