How can I delete this db entry

When trying to upgrade my nextcloud version 21.0.3 , I got this error:

Updating database schema

InvalidArgumentException: Migration step 'OC\Core\Migrations\Version13000Date20170705121758.sync-conflict-20210821-091122-3JOCVPS' is unknown

Can anyone tell me which table in the nextcloud db will this entry be , so I can get rid of it ?

this probably got in the db table as I am using syncthing to keep to nextcloud/data folders in sync between 2 nodes.
