vCenter 6.5 html (flash) function, comparing with vSphere client

Hi,

I just upgraded the vCenter from version 5.5 to 6.5, so I just have the html (flash).

I discovered I cannot / not working to do some functions on the html (flash), comparing with the vSphere Client.

1. CD/DVD Device to connect the Local Disk ISO through Console (Cannot map the ISO on local disk on console of vCenter 6.5)

2. can Export the OVF, but it cannot Export to be OVA (Cannot export the OVA on vCenter 6.5)

3. Deploy ova template fail on the ESXi host 5.5 through vCenter 6.5. When I disconnected the management of vCenter 6.5, it was successful to deploy the ova from ESXi host directly.

Should I select the 'Deploy OVF Template' on vCenter 6.5?
