You could, I believe, turn off auto-negotiation and set it 1G full duplex on both sides and then add the links in and then remove the old 1G's when ready then remove auto-negotiation from the 10G

But, it would ultimately be much, much easier to create a new LAG and then take an outage on ovirt and move everything to the new one

Hi,

JunOS supports LAG over links with different speeds, so if you have MX
series routers in-between, you can try to accomplish that.
But it's always better to be on safe side, it's very risky to use in
production, IMHO.

Best regards,
