Migration From Vmware using the new migration tool.

[admin55]

Hi I am very close to making the switch to proxmox from vmware. I think I have watched every migration video and just one questions.

In regards to adding ESX as storage. Don't I also have to add my iscsi san as well so proxmox has access to the vmware datastore or is that the adding esx part?

The challenge I have is that i am about 60% utilization on my san and I don't have enough room to create a NEW proxmox datastore on my san and then migrate everything to a new proxmox storage on the same SAN.

Am in understanding this correct that proxmox using the importer tool converts the VM and keeps it in the same vmware datastore but accessed by proxmox? What happens after the esx host goes away is there another step i have to do by moving the disk?

Thank you for your help.

Hi @admin20, welcome to the forum.

You can, but you don't strictly need to. The ESX Migration tool uses ESXi API to extract data from ESXi and then transfer it to the PVE. That obviously means that you need somewhere to put that data in PVE. It could be iSCSI SAN datastore/pool, or something different. If you decide to stick with your iSCSI SAN - the LUNs you present to PVE must be new and separate from the LUNs you presented to your ESXi.
Since you don't have enough space, you may need to find a way to do a staggered migration. Perhaps, buy a few local Enterprise Disks to keep data there for a brief period.

This would be an incorrect understanding, see above.

What happens after the esx host goes away is there another step i have to do by moving the disk?

Once you migrated all of the data from ESXi, you can delete the ESXi LUNs and re-assign the space elsewhere.
