    have you checked the following articles: 

    Upgrading host from vSphere ESXi 6.x to 7.x datastores may become overwritten if incorrect scratch location is set, prior, or after upgrade (83647) (vmware.com)

    What Storage vendor do you have? 
    In which way you have created your Datastores? FC, iSCSI or FCoE?
