SAP R/3 HW migration steps

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 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 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,
