As per Telegram, I agree with Strit and Freggel: expecting a 5 year old rolling release to still update to today in one go is going to be impossible as the full delta from then till now doesn’t exist any more.
Therefore, create your own VM from the most recent version and then keep it updated as Manjaro is a rolling release and you might be able to skip one or 2 updates, but not 3 and certainly not 10, because that’s not the architectural design of Manjaro.
If you need a distro that you only have to upgrade every couple of years and apply security patches only in-between upgrades, take something like Debian or Ubuntu: they still use a waterfall method to upgrades…
