Moving Hardware from RHEL5 - RHEL6

[former_member201800]

Hi,

Scenario -  I want to migrate my ECC EHP5 Application Server from below OS Release to below 'Target OS Release' on different boxes.

Current OS Release -

Red Hat Enterprise Linux Server release 5.9 (Tikanga)

Linux 2.6.18-348.6.1.el5 #1 SMP Fri Apr 26 09:21:26 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux

Target OS Release -

Linux 2.6.32-504.12.2.el6.x86_64 #1 SMP Sun Feb 1 12:14:02 EST 2015 x86_64 x86_64 x86_64 GNU/Linux

Red Hat Enterprise Linux Server release 6.6 (Santiago)

Can we perform this migration by unmounting all File System from existing  VM and mounting all the directory and file structure (SAP & DB) to New VM ?

or

There is only one option to migrate the system i.e. using DB backup and restore / System Export-Import .

Please suggest.

Regards,

Shyam Kumar

Filesystem level clone is not officially supported in SAP migrations. You should uitilize SWPM tool to perform either homogeneous system copy or heterogeneous system copy. Systemcopy guide can be found from service.sap.com/instguides.

Checked from support.sap.com/pam page, EHP5 is supported on both RHEL 5/6 even 7. You may want to prepare the box following note below before starting.
