Hello,
Since PeopleSoft was installed initially on your Windows-based or Novell file server, you do not have to do a reinstall of PeopleSoft. Simply copy/FTP the file from the file server to your Solaris server.
If everything is messed up completely, simply run the Server Transfer or Batch Transfer process again and place the files in a different directory. Reconfigure a new application server domain and process scheduler server agent from the new directory and move forward.
Good luck.
