Physical movement of SAP Server and Pre,Post steps ?

Hello Experts,

Need your help here..  Our Data Center is moving to Different Place  , hence IM team proposed Physical movement of SAP Server to New Location.

In our Landscape we have SRM 4.0, XI 3.0 & BW 3.5 , ITS 620 and Requisites Servers available . As these are out of  SAP support we don't have expert for ITS and Requisite Server installation and configutaiton.

Please  please  tell me Will this process work ? if yes then what are odds n cons in this procedure , Pre and Post Steps need to perform.

Please help me as early as possible as we need to take decision ASAP.

Thanks and Regards,

Raja.

Hello

What matters is the host name.

If you are going to retain the same hostname for all the machines then everything should be fine.

You might need to install new SAP license if there is a change in the hardware key.

You might need to update the IP address in the SMP and also in the SAP router saprouttab file.

Hi Raja,

You need to take care of following

1) Ensure that IP address and hostname are retained in the new DC. If IP is changing you need to take a note of all the RFC and JCO connections where IP is used and replace them with hostname.

2) For ITS you can re-install and re-configure. It is not a big task.

   Make a note which all places ITS is configured.

3) You need to have full offline backup of the system before movement.

4) You need to plan for some System integration testing post movement to ensure things are working post DC migration.

Some useful information can also be found in http://christian.bergeron.voila.net/DC_Guide/Data_Migration_Methodology_for_SAP_V01a.doc

Hope this helps.

Thanks Deepak,

For quick reply !

I have checked with IM team about IP's  but they said IP's can't be retained. So if this is the case did we need change any particular place except RFC's ? like registeries ?... etc.

Any other steps needs to be consider before movement of Physical server.

Thanks ,

Raja.

Hi Raja,

You may look into places where IP is maintained viz

- RFC

- If DB is oracle then, listener.ora file entries

- Visual Admin configuration

- host file entries

- SAP router IP needs to be re-registered with SAP

- Updating SAPlogon pad entries for users where IP is maintained

- Updating printer entries created on OS level

Hope this helps.

Hi Raja

You can change the new set of IP's in your new location. but the SAP Physical server name should be same on your old location. and also you have delete / Clear the old set of IP's in DNS Server and local Host file  (Old location IP)

You can have local host file entries based on new location kindly refer the SAP notes for IP address configurations 403708 - Changing an IP address
