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

You can use warm migration to solve this. Also, we provide pro support and services to help you to migrate, it's probably a lot of time saved with our expertise

I have tried this over XOA, but it does not work with even a cold migration where the VM is shut down.

This is the XOA error I receive when trying to go from XS8 (DBV 2024.0229) to XCP-ng 8.3 (build date Oct 11, 2024 4:26:51 AM / DBV 0.0.1 reported).

We use XOA Enterprise 5.103.0 in this environment but would be planning to use XCP-Ng 8.2.1 community for these VMs in particular.

If the recommendation would be to open a support ticket from my XOA account to help ease this process, I can do so. ...we were hoping XS8 would keep an indefinite trial, but that has been shown to not be in Citrix's interests.

I've got a similar situation to this thread.

Currently, we have a mix of Citrix Hypervisor 8 (8.2 CU1 LTS), which is going end of support later this year. We use a mix of standard license and xenserver express licenses.

I've been testing out migrations to both XenServer 8 through Citrix and XCP-Ng, but most of the staff I work with primarily use XenCenter for managing VMs, and XCP-Center hasn't quite had the ability to keep up with recent changes. We do have XOA as well, but as we make use of importing/exporting VM images quite often, XOA doesn't quite work work well here, which would mean having to have XenCenter for our licensed VMs and XCP-Center for our unlicensed ones if we go with XCP. But that's a tangent for context.

What I've noticed is that I can upgrade from CHU8 to XS8 or XCP 8.2.1 fine, but there doesn't appear to be any way to "upgrade" or migrate from XS8 to XCP8.

And exported XVA files from XS8 cannot be imported to XCP 8.2.1 or 8.3, which is a blocker if we want to fully migrate to XCP to keep our environment uniform.

If I put in a XCP-Ng ISO (either 8.2.1 or 8.3), it does not offer the ability to upgrade from a XS8 install. XOA is also unable to copy a XS8 VM over to XCP 8.3.
