We need to delete OID Authentication

HI we were using OID for authentication but we had password issue so we configured MSAD now all user are login through MSAD I need some clarrification on the below,

As per our client suggestd we dont want OID so we need to delete OID, but users created data forms and grids through OID authentication with their user ids, If we delete OID all data forms and grids will be availiable or that also wll be detlet?

Please let us know on thease because this will be in the production environment for reference please find the attached document.

Thanks,
