Although sometimes there may be no issues, there is no guarantee and the upgrade can result in various types of incompatibilities that can range from minor to severe, and it may be very difficult to troubleshoot. This includes the opkg package manager, which does not have built-in ABI (Application Binary Interface) compatibility and kernel version dependencies verification. Unlike the 'big distros' of Linux, OpenWrt is optimized to run on systems with limited resources. opkg upgrade will not update the OpenWrt version. It is also important to stress that this is distinctly different from the sysupgrade path for upgrading OpenWrt releases (major versions as well as maintenance upgrades). In particular, bulk upgrading is very likely to result in major problems, but even upgrading individual packages may cause issues. It should be avoided in almost all circumstances. Generally speaking, the use of opkg upgrade is very highly discouraged. The same warnings apply to upgrading packages using LuCI and the CLI. The LuCI Upgrade… button performs the same opkg upgrade command that is discussed in this article. Both methods invoke the same CLI opkg executable, and as of OpenWrt 19.07.0, the LuCI interface now has an 'Updates' tab with a listing of packages that have available upgrades. There are two ways to manage/install packages in OpenWrt: with the LuCI web interface Software menu (System > Software), and via the command line interface (CLI). Inform yourself before doing any upgrades to determine if it is safe to upgrade. Just because there is an updated version of a given package does not mean it should be installed or that it will function properly.

The sysupgrade verbose-option should give some output similar to this.
