+How can I upgrade {pve} to the next release?::
+
+Minor version upgrades, for example upgrading from {pve} in version 5.1
+to 5.2, can be done just like any normal update, either through the Web
+GUI __Node -> Updates__ panel or through the CLI with:
++
+----
+apt update
+apt full-upgrade
+----
++
+NOTE: Always ensure you correctly setup the
+xref:sysadmin_package_repositories[package repositories] and only
+continue with the actual upgrade if `apt update` did not hit any error.
++
+Major version upgrades, for example going from {pve} 4.4 to 5.0, are
+also supported. They must be carefully planned and tested and should
+*never* be started without having a current backup ready.
+Although the specific upgrade steps depend on your respective setup, we
+provide general instructions and advice of how a upgrade should be
+performed:
