!!! warning "Existing Deployments Must Upgrade from v2.11"
Upgrading an existing NetBox deployment to version 3.0 **must** be done from version 2.11.0 or later. If attempting to upgrade a deployment of NetBox v2.10 or earlier, first upgrade to a NetBox v2.11 release, and then upgrade from v2.11 to v3.0. This will avoid any problems with the database migration optimizations implemented in version 3.0.
