Importing cPanel VMs from VMware: Max size of IDE disks under Proxmox?

I've been importing a set of cPanel VMs from VMware to Proxmox.

The VM running CentOS6 migrated perfectly and came up on first boot attempt.

We have several more running CentOS7. Most of those required the fix where they fail to boot on initial import, so you shut them down, detach the disks, re-attach the disks but as IDE not SCSI, and then they boot fine and run happily. So far four have been successfully imported this way, all of which had 100 or 200 gig drives.

We have one final one, also running CentOS7, and this one has a 1TB disk. I gather this is lager than physical IDE disks were actually made, so wondering if likely to run into any problems, or will Proxmox be find with a 1TB virtual IDE disk on a VM? We always try a boot before changing the drive type, but so far only one CentOS7 machine booted with the disks left as SCSI, all others needed the detach/attach trick so am expecting to have to use the fix on this one too.
 
Update: It worked. As expected, the VM wouldn't boot with the disks set to scsi, so shut down, detach disk, then edit the disk and re-attach it as IDE, VM boots fine, and having a 1TB IDE disk doesn't seem to cause any issues.
