How can we change the owner of reports processes and scheduling that will be coming inactive to a different user?

Hello,

We have BI and OTBI reports that programs that were created under one user of an employee,
and scheduling under the same user.
The user who created the reports and processes will be inactive soon ,and we would like to
move all the reports and processes under another user.

How can we have all reports and processes run under another user if the owner user of the will be inactivated
without damaging the scheduling .

Thanks
Revital.
