We currently have SAPPRD and we are doing a system copy to a new system .

Once this is done , we want to maintain the same SID, same Sysname and same IP address as SAPPRD is currently having and convert the existing SAPPRD to APP3.

Can any one suggest how to do it and any work around to minimize the conflicts.

Simple. Follow the note on Sapnet regarding homogenous system copy and server migration.
All you have to do is take the new server, install SAP and oracle binaries (of the current version, or upgrade prior to this task). Then copy the system, rename the NICs/DNS from the old system, then do the same for the new system. Start the new system up and it should be running and you can continue your work. Then delete the old installation from the old server, and reinstall sap binaries, then include the server in the logongroup.
It IS however easier to change the IP adress or have the network "forward" the old IP adress to a new one.
Ensure that you've testet all of the external communications interfaces. This is a common mistake to make.

ad1) You shouldn't see a difference except in the prereqs. The reciveing end must ofcourse also have unicode installed.

ad2) I dont really understand the question. Do you mean if there's anything else you should be aware of in case you'll be doing a homogenous system copy of aa unicode converted system ? If that's the case, then I'd say no. There's no difference with regards to unicode. The procedure remains the same. Ofcourse some applications may have issues with a potential new hostname, SID name etc. and may require some tweaking, but that's usually caught in the first test. The guide pretty much covers everything that'll make the system (non-)functional.

3) Offhand, none it' sthe same process regardsless. That said, I've never seen the need to complicate things and use it.
