Can we change hire date of employee and add a contractor assignment prior to hire date.

Summary:

Employee was a contractor hired on 19/7/1999 and converted to Employee on 1st June 2016.

But while converting the data to Oracle cloud from legacy system, during conversion this employee was directly hired as Employee with Hire Date 19/7/1999.

Client wants to correct the assignment date to start his employment from 1st June 2016 as an employee and create a Contingent worker row from 19/7/1999 to 31st May 2016.
