Filesystem change when migrating from Windows to Linux

Hi Gurus,

Our ECC landscape is migrating from Oracle / Windows 2008 R2 to  Sybase / Red Hat Linux  6.4 64 bit &


However we have a lot many customer /vendor filesystems which are connected to our SPA system.  Most of these are used to place data from other non SAP systems or EDI and in some cases invoices / PO's.  These Filesystems are called via various function modules as and when the output files need to be placed in these Windows filesystems.

Our concern is how do we access these Filesystems from the target Linux system without significant codes changes in function modules  where the paths are hard coded.

If we mount these Filesystems on the Linux box, they can accessed for sure, but this would mean lot of changes in the nomenclature [ forward slash "\" replaced by backward slash "/" ]  in the path for these FS and also code changes for a lot of functional modules.

Could you share your experiences of how you managed the changes in FS  during the OS/DB Migration process.

Warm Regards

For a quick and dirty way, setup one (maybe more depending on the number and location of your business directories) soft link on the linux server after it is setup to reach the old Windows server.

This will give you two things, that the file structure is the same (for the most part) as you are just linking back to the Windows system; and will allow for a slower migration of the business directories providing you more time to focus on the migration of the OS/DB/SAP project.

Hi Prashant,

During OS/DB migration from Windows to Linux best approach to identify all such filepaths which may undergo a change due to change in OS platform.

Post migration all these changes needs to be performed manually in one of the systems. Later these changes can be transported to remaining systems in SAP landscape.

Hope this helps.

Hi Deepak,

We have already identified the filepaths , but changing them manually in SAP ABAP / function modules looks like a herculean task.

This is because, our filepaths vary as per our suppliers and customers/vendors , plant numbers, type of material, and also we have many Filesystems to which our ECC system writes data to.


Manual changes would require us to change variants / programs and functional modules for many paths and this is an  immense amount of effort.


Is there any alternative method of doing this.


Warm Regards

Hi Prashant,

For any kind of hard coding effort is required to restore them to new environment.

May be as a part of this migration project you may think to optimise the code so that in future such situations can be handled efficiently
