Getting a bit stuck on a site upgrade from 3.4 (184.108.40.206). After updating via composer getting DB errors.
Integrity constraint violation: SQLSTATE: Integrity constraint violation: 1062 Duplicate entry 'startDateTime-global' for key 'craft_fields_handle_context_unq_idx'
If I try to restart process (overriding the "It looks like someone is currently performing a system update" warning):
Database Exception: SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'elements' The SQL being executed was: ALTER TABLE craft_fieldlayouttabs ADD elements text AFTER name
Any thoughts on resolving?
