vCenter can't access VMs with Thick Provision Lazy Zeroed disk

[pgosselin82akp]

Hi. sorry for bothering u guys but I need urgent help.
I got this warning: There are compatibility warnings. The operation is not supported on the object. Disk '2000' is not moving, so any transform requests will not be honored."
I updated our Freenas to TrueNas stable, and all VMs were broken, I fixed many of them unmounting the CD drive but those VMs with disk type Thick Provision Lazy Zeroed are still unable to boot.

Tried to convert from vcenter command line from thick to thin type fails with no permissions. 

Do u have any idea about how to fix it?

Thanks a lot in advance

what do the last few lines of vmware.log in the  VM directory specify? Also, can you export the VMs to another datastore and while migration change the disk type from thick to thin ?
