NetBox version

v3.3

Python version

3.8

Steps to Reproduce

Tried to Upgrade our instance and run into:

File "/opt/netbox/venv/lib64/python3.8/site-packages/django/db/backends/utils.py", line 87, in _execute
return self.cursor.execute(sql)
psycopg2.errors.UniqueViolation: could not create unique index "dcim_device_unique_name_site"
DETAIL: Key (lower(name::text), site_id)=(dus2-x-ac1, 3) is duplicated.

Expected Behavior

Upgrade runs fine or renamed objects

Observed Behavior

psycopg2.errors.UniqueViolation: could not create unique index "dcim_device_unique_name_site"
DETAIL: Key (lower(name::text), site_id)=(dus2-x-ac1, 3) is duplicated.

The above exception was the direct cause of the following exception:

You have multiple devices assigned to site 3 with the variations of the name dus2-x-ac1. This is preventing the migration from completing.
