SAP R/3 HW migration steps

Question

Dear all,
We are purchasing new servers for our SAP R/3 environment, because current one's are almost five years old.
SAP R/3 4.6C on Oracle 9.2.0.5 on HP-UX 11.00
I was wondering about this procedure for SAP application and DB copy to the new server.
What do you think about the following steps on the new server:
1. HP-UX 11i v2 installed,
2. File systems for /oracle/SID...., /usr/sap/SID..., /sapmnt/SID... created.
3. users sidadm and orasid environment variables - copy the same from the source
4. Install Oracle 9.2.0 with the patchset 9.2.0.5 like the source databases,
5. /etc/passwd, /etc/services, /etc/group copy the corresponding lines from this files
6. rcp from current server to the new one the file systems:
   a. /oracle/SID
   b. /oracle/SID/sapdata*
   c. /oracle/SID/mirrlog*
   d. /oracle/SID/orriglog*
   e. /oracle/SID/sapreorg
   f. /oracle/SID/saparch
   g. /usr/sap/SID
   h. /sapmnt/SID
7. Change hostname on the SAP profiles, sidadm profile files, .profile, .login, .dbenv, .sapenv , orasid user profile files .dbenv_<host>.sh and .dbenv_<host>.csh in the home directory of ora<dbsid>.
8. /home/sidadm startsap_... stopsap_... scripts change the hostname for the new server
9. listener.ora and tnsnames.ora change
10. SAP license installation of temporary license, until the successful migration
Can I do the SAP system copy from one server to another like the above procedure?
Thank you all.
Many regards,
Ruzica

Dear all,
Can You PLS look at my planned steps for TMS reconfiguration?
Is this ok?
For QTS and DEV.
1. Logon to the target system as user " SAP* " in client 000.
- Run transaction SE06 and select the radio button "Database Copy" and
click on the "execute" pushbutton.
- source system of database copy = (the same SID)
- Answer "yes" to everything
- Change all objects from <sid> to <sid>
Ans "yes" for "Delete TMS configuration" & "Delete TMS transport route
NB.
Should I delete (with SE06) the TMS configuration for PRD also (the transport domain)?
2. STMS from DEV and QTS and delete all systems.
3. STMS from PROD (client 000) if I was deleted the TMS config now I should create three system landscape with ProdQTSDevelopment and create the transport routes manualy
I have saved the transport route config
4. From DEV and QTS client 000, STMS -> other config -> Include system in domain
5. From PROD STMS->Overview systems -> select DEV -> SAP System -> Approve
and also select QTS -> SAP System -> Approve
6. Should I delete the RFC connections
[email protected]_PROD [email protected]_PROD before deleting the TMS config in PROD?
THANK YOU in advace again
