            Hi!

            We are pretty busy here (at Vates) about 8.2.1 new ISO and 8.3 release. We'll be happy that anyone around in the community is able to assist!

              @olivierlambert understand.
              Please let me know if I can help trigger people to support on that.
              It seems that this topic has already a little dust on it - so I am happy to collabortate.

              In the meantime, I made some Tests and will provide the last lines from the debugging.

                    I understand that there is a big GoLive on your side.
                    Do we have alternative suggestions to migrate from xen to xcp-ng?

                      The other alternative, if a bit cumbersome, is to use Clonezilla, like a P2V situation 🙂

                        I also worked on trying to update the script to python3 last week and hadn't realised you had this work here so was starting from scratch.

                        I am not a python developer so when I got to errors in the section that is actually streaming the files I decided to stop and just finish 'making' python2.7 on the servers that I need to get the VMs off and that has worked for me.

                        It doesn't seem like it should be a huge amount of work left to upgrade the script to python3 but probably not something I have the skills or time for right now.

                        Thanks for sharing your efforts here. What have you ended up doing @josef1909

                          Thanks for re-pinging. This might be a "simple" mission to finance to a Python specialist. Let me add @AtaxyaNetwork in the loop.
