To help with this - and upgrading in general - we have also released a video tutorial of the IXP Manager v5.8.0 to v6.0.0 upgrade process which includes upgrading to PHP 8 on an existing system (e.g. Ubuntu 18.04 in the video) and a second option of upgrading to Ubuntu 20.04 and then to PHP 8.0 - https://youtu.be/KcWUMYCQosA

Thank you all for your hard work on IXP Manager.  Quick question, do I need to be on 5.8.0 to upgrade to 6.0.0, or can we go from 5.7.0 and skip the 5.8.0 upgrade?
