      @olivierlambert Can we just stream it like fire and forget as long it can identify the default SR?

        @josef1909 I just need to go ahead to check if the script will send more issues I need to work on.

              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.
