I need to upgrade our DEV and TEST instances but I don't see an option to upgrade to Xanadu.

Hi @DavidL065538777, 

Please check the ServiceNow support portal, there must be default CHG created for all of your SN instances.

If you have other schedule for your instance to be updated , then open the CHG ( default one ) and update the schedule start/end timelines.

Also if there is no change ( or not visible ) to your, you can open case, or you can create new upgrade CHG for DEV/TEST.

Note: Upgrade is scheduled on Support portal not on SN instance. 

-Thanks,

To update, you need to raise the request via partner portal, and then you can select the date and time, also, do cloning before go for upgrade.
