SAP ECC Migration from Physical to ESX

Former Member

Dear All,

My company is moving from Physical Servers to Virtual Platform (Vmware ESX). We are using 7.2 kernel on RHEL 5.3 64 bit for SAP HCM. My plan is;

1) Shutdown all services

2) Clone Physical Server into VM using vCenter Converter

3) change all DNS Base information and update IP address

4) Restart the services on new server with new IP Address

My take is i need to request new License for new Hardware. Please suggest me what else i need to consider during this process.

Thanks.

Hi,

My take is i need to request new License for new Hardware

Yes you need to request for new license since your hardware is changing.

Apart from the steps mentioned by you,

1) You need to readjust the RFCs

2) Adjust the TMS configuration

3) Adjust the SAPlogon pad entries for endusers.

If your initrd is very thinned out, you might add modules for LSI Logic virtual SCSI adapter (should be mptspi and dependants). Installing VMware Tools before powering on the virtual machine on vSphere can also be an option. Be aware that SAP databases don't allow changing their physical hostname, although you can add external aliases, but the reverse lookup should always give back the old hostname. If you run into troubles, consult VMware KB 1004588. Currently, only VMware Converter 4.2 and above support physical to virtual machine conversion for Linux sources.
