I'm thinking of buying a Ubiquiti EdgeRouter-X because I need a cheap router with no need for wifi which is easily flashable. While looking through the instructions I saw an adjustment of the partition layout was needed (https://openwrt.org/toh/ubiquiti/edgerouter_x_er-x_ka#migrating_to_2410x).
Is this a one-time process or do I need to re-use the script for every update? So for example: the current release the script uses is 24.10.1. When this upgrade is done, I can use the sysupgrade function to migrate to version 25.10?
Once you install OpenWrt, you can upgrade using OpenWrt’s upgrade processes.
Rather than using sysupgrade, consider using owut:
The difference is, sysupgrade downloads and installs the stock firmware. So if you installed any additional packages, you will have to reinstall them after syspgrade completes and device reboots. owut adds a step in the beginning: it takes a list of packages installed, then, goes to an online build server and says, “Please build me firmware with this package set”. Once the build is complete, owut engages sysupgrade to download and install that custom firmware, rather than the stock version with the default package set.
My understanding is that luci-app-sysupgrade works the same way as owut. That is, it gets the ASU to build the same firmware packages as was installed.
Yes (I believe, as of release 24, Attended Sysupgrade is a Web front end for owut; before that, it was a Web front end for the predecessor utility called auc), but owut is much more informative. It shows you what it does step by step and if it encounters a problem, it usually can explain what the problem is.
