OnePlus lays out plans for updating OnePlus 6 and later models to Android 11

Update schedule could vary for Verizon, T-Mobile, and EE models
The Chinese manufacturer will start rolling out the first OxygenOS 11 Open Beta build to the OnePlus Nord next week. It will use user feedback to iron out any bugs before the public launch. The deployment will be staged and the timeline could vary for carrier-locked variants. The company says it will work closely with telecom operators to send out updates 'at the earliest possible date.'
OnePlus also plans to bring the OnePlus 6 and 6T, and Nord 10 5G and 100 to Android 11 eventually, but it hasn't disclosed a timeline for these devices.
