How to upgrade Linux Mint 18.3 to Linux Mint 19
If you are using the Linux Mint 18.3 “Sylvia” system and want to upgrade to the latest Linux Mint 19 “Tara” system, today the upgrade channel has been officially opened. Following the official release of “Tara” and the three major versions of Cinnamon, MATE and Xfce, the Linux Mint development team announced that the upgrade channels for all three major versions of Linux Mint 18.3 had opened, but unfortunately, the KDE version will no longer be supported.
However, this upgrade is only for users who want to explore new features or need to fix some issues with Linux Mint 18.3 “Sylvia”. After all, Linux Mint 17 will continue to support until 2019, and Linux Mint 19 will support until 2021.

“You might want to upgrade to Linux Mint 19 because some bug is fixed or because you want to get some of the new features. In any case, you should know why you’re upgrading.
As excited as we are about Linux Mint 19, upgrading blindly for the sake of running the latest version does not make much sense, especially if you’re already happy and everything is working perfectly.”
