After installing new environment of vCenter Server Appliance 6.5 version, we encountered an issue while importing OVA file. The wizard stopped progressing and thrown an error - "OVF package with compressed disks is currently not supported for OVF import."
You must have also faced this issue if incase you upgraded appliance version to 6.5
This issue is listed as unknown issue in VSphere 6.5 Release Notes and as a workaround, use OVF tool to convert the OVA or OVF template. The new template will not have compressed disks.
- Download and install OVF tool
- OVA template conversion (incase of .ovf template, follow the same syntax however change the extension to .ovf)
C:\Program Files\VMware\VMware OVF Tool>ovftool.exe ova-template-name.ova newova-template-name.ova
To fix it permanently, upgrade your vSphere to 6.5U1b.
