Tired using this doc , but did not succeed. Database Migration From Windows to Linux Using RMAM by Alejandro Vargas | Principal Support Consultant I want to use Rman to do this process rather then imp exp. So if anyone have exact steps for the process, I am trying this on small default database first, then would go on for the production. Please if anyone could shed some light over this it would be helpful. Thank you.
