How to minimize downtime to add Oracle HR Module
We are using Oracle E-Business suit (Application 11.5.9, database
9.2.0.3), Modules are 1) Project Accounting, 2) Inventory, 3) Purchase,
4) Financial (AP,AR,GL)
We are in process to implement Oracle HR and Payroll module, to do so we have to upgrade the database to 9.2.0.8 and also some part of the application.
We have downloaded all the Patches and applied in the TEST instance, patch application time was 10 to12 days. practically it is not possible to down the Production Instance for 10 to 12 days.
Please suggest us the process to minimize the downtime.
