VMware migration tool: we need your feedback!
Perfect! Now expect all of this but in a simple wizard in the UI, that will be a great tool for everyone who want to make the migration (and we hope to get a decent share of those users with our new support bundle)

After running for hours, get the following

@severhart the sesparse format is used for disk greater than 2TB , and for all disks after esxi 6.5 , and it's not very documented
we are working on implementing this reader to allow migration during Q1 2023
For now esxi 6.5+ vm are limited to migration of sopped vm without snasphots
@florent thanks! for the fast reply, I will take the outage and rerun, and let you know outcome.
Also, 2TiB+ disk can't be imported since it's limited to 2TiB tops on XCP-ng default storage stack.
@olivierlambert Would love to see some way to have it import larger than 2TiB disks as multiple disks in XCP-ng, since most OSes just let you span drives anyway.
Just realized I may not be able to leave VMWare with this method since one of the disks on a VM I'm trying to move is over 3TiB.
We could detect 2TiB+ drives and create a
rawdisk on our side, but it won't support snap nor live storage migration.
Only another format (used in SMAPIv3) will allow us to solve this.
@olivierlambert Gotcha, this makes sense.
Is there any way to skip a specific drive with this migration script? I'm thinking I could skip the larger than 2TiB disk and then just create 2 x 2TiB disks after migration, span them in Windows, and then copy the data manually from the VMWare VM.
I think we could probably skip it (since it's likely not a system disk) so you can then manually copy the rest the way you prefer. We should probably add an option like "just skip 2TiB+ disk without failing"
@olivierlambert Yes, I think that would be great, this would be a good workaround for people that have larger than 2TiB disks.
@olivierlambert Also, do you know if the disk is OVER 2TiB thick provisioned but actual data usage on it is like 1TiB, will the script still fail or will it just create the 1TiB disk?
The problem by doing that automatically is you can have bad surprises. We'll probably just skip it after adding the option.
@florent none of the drives are over 2tb, largest is 900GB, so I will assume it is due to snapshots?
@severhart as Flo said, it's because of your VMware version (6.5+) that is using another "diff" format not yet supported. In your case, you should do a cold migration for now, until we support this diff format
Total noob here jumping in at the deep end.

Hey @magicker can you give us more details? Are you using XOA or XO from the sources? At which version? Also on VMware side, what's your ESXi version?
@olivierlambert said in VMware migration tool: we need your feedback!:
XO from the sources
XO from github (2 days old)
esxi .. 7.0.0 (Build 16324942)
olivierlambert Vates 🪐 Co-Founder🦸 CEO 🧑💼
So the diff for warm migration isn't supported on ESXi 7.0 (yet!). So your VM must be halted first (on the VMware side I mean)
you should also have additionnal logs in your xo logs
Thank you for testing it
