Hello, I'm currently in single version, I would like to know how to upgrade to server version without resetting my ISPConfig. Thank you,
You can either add a slave server, or setup a new multiserver setup and use the migration tool to move your installation.
install a new server following the relevant perfect server tutorial, all the way up to the point of installing ispconfig itself. add the required root users and privileges to the existing servers mysql instance, for both the new servers name and ip, according to the instructions near the end of the 1st page here: https://www.howtoforge.com/multiser...se-servers-on-debian-squeeze-with-ispconfig-3 download and install ispconfig as per the tutorial. choose expert mode, and choose to join an existing multi-server setup. give it the relevant details to connect to the original servers mysql instance, and then tell it to configure ( or not configure ) whatever service you want ( don't want ) to use on this new server.
