I have ERPNext running on Ubuntu 14.04.4 LTS server. The version of ERPNext is 10.1.40. The version of Frappe is 10.1.37. My ERPNext service is operational and maintains a large amount of data in process, so i can’t lose anything and i need to do this procedure directly on it. To carry out previous tests I use a VM copy in VirtualBox.
I would like to update my ERPNext service from version 10 to version 12, but first updating the OS an Ubuntu 18.04 LTS.
Can someone guide me on how to perform this procedure? Tips, help, links, all
information is useful.
Thanks you very much.
