      @psylo said in XenServer-8 to XCP-NG:

      Hello,

      I'm quite new to all of this so sorry if I'm making mistakes.

      We currently have a pool of 3 servers on XenServer 8.4 (so 8.3 if I understood properly) on which we applied almost all updates lately, hosting around 10 VM.
      The countdown message is displayed in XenCenter and after discovering it we planned to migrate to XCP-ng.

      I've followed the instructions and I tried to boot on the 8.3 iso, but when I do so there is no choice to migrate from XenServer but rather to install XCP-ng, is it the same ?

      If it's not the same what choice do I have ? To install XCP-ng on one of the server and then migrate the VM to it using export/import, to then rebuild the pool on XCP-ng ? Unfortunately I don't have any other spare servers to use so I'm quite restricted in what I can do, and if possible I'd like no downtime.

      The only way I found to migrate is export to OVF format using XenCenter, install XCP-ng from zero and after import all VM's using XCP-ng Center.

      @ricardowz Are you able do attach the vhds (vdi) to a new vm after reinstalling with xcpng. so no import but using the old files.

      if this works you could export the vdi to a vhd or raw and reimport it.

      We didnt update to the latest xenserver version so according to your test we may be safe, but what i dont want is to reinstall with xcpng an than the vms are dead.

      we have an old server so i may install xcpng there and migrate over from xenserver. than migrate back afterwards. but this is all very time-consuming in that situation.

      Is your XenCenter displaying the countdown message?

      The current Trial Edition license expires in ... days. You will not be able to start VMs after expiry.

      If it's, I think the in place migration is not gonna work for you to. For me, it looks like it does not matter if it's not on the latest version, but if you installed some upgrade after initial installation of XenServer.

      Hi!

      We have some hosts with XenServer-8 Trial Edition. XenServer limited the runtime to 90 days so we cannot update anymore to avoid this.

      Is there an easy way to migrate to XCP-NG without Backup/Restore or Export/Import of the VMs?

      We would prefere XCP-NG 8.2 but if this is not possible XCP-NG 8.3 is also an option.

      I have already read to docs but i am not shure how the migration is when you come from Xenserver-8
      We do not use any not supported fs (GFS,XFS). We use ext4

      XenServer Version according to XO: XenServer Trial Edition 8.4.0 (trial)

      Greetings!

      I tested in two different situations:

      1. From XenServer 8 without upgrades and without the remaining time warning, just basic installation and 1 VM created, to XCP-ng 8.3: it worked OK, apparently.

      2. From XenServer 8 with all available upgrades and with the remaining time warning to XCP-ng 8.3: IT DID NOT WORK.
        Problems found: the management interface is not available;
        other, on xsconsole, when try to access menu Virtual Machines > All VMs, an error message is shown: 'NoneType' object has no attribute 'xenapi'

      Somebody can help solving these questions?

      I am testing other options, like export all VMs, make a clean installation of XCP-ng and import all VMs back.

      I tested using XCP-ng versions 8.2.1 and 8.3, and in both cases I could not import the VMs exported from the XenServer, this error message is shown:
      The import failed because this export has been created by a different (incompatible) product version

      I am using the .xva format, I did not try other format until this moment.

      So, until now I could not migrate from most recen XenServer version to XCP-ng.
