[[faq-upgrade]]
How can I upgrade {pmg} to the next release?::

Minor version upgrades, for example, upgrading from {pmg} version 5.1
to 5.2, can be done just like any normal update, either through the
__Node -> Updates__ panel or through the command line with:
+
----
apt update
apt full-upgrade
----
+
NOTE: Always ensure that you correctly set up the
xref:pmg_package_repositories[package repositories], and only continue with the
actual upgrade if `apt update` did not hit any errors.
+
Major version upgrades, for example, going from {pmg} 5.4 to 6.0, are
also supported. They must be carefully planned and tested, and should
*never* be started without having an up-to-date backup ready.
Although the specific upgrade steps depend on your respective setup, we
provide general instructions and advice on how an upgrade should be
performed:
