ERP 6.07/Oracle 11 migration to 6.08/HANA on Solaris using DMO

[murray_lahn]

We are wanting to look at migrating a client's ERP 6.0 EhP7 running on Solaris and Oracle 11 to a HANA database using the DMO option to accomplish this.

However, when we looked at it further, I see that in the PAM, it appears that while EhP7/Solaris/Oracle 11 is supported, and while Solaris (app)/EhP8/HANA is supported, EhP8/Solaris/Oracle11 is not (you must be on 12).

From a DMO/SUM upgrade/migration then, the interim steps during the DMO would look like:

1. Solaris, EhP7, Oracle 11
2. Solaris, EhP8, Oracle 11 << NOT SUPPORTED
3. Solaris, EhP8, HANA
4. .Then we switch the app server over to Linux and have Linux, EhP8, HANA

My suspicion would be then that I might run into issues during the DMO when we get to the 2nd step.

My question is, is this a correct assumption?

I know we can mitigate this by either a) upgrading to Oracle 12 first, or b) doing the EhP8 update after, but were hoping to be able to do this in one step using DMO if possible.

Thoughts?

Hi Murray,

according to the SAP note

2277055 - Database Migration Option (DMO) of SUM 1.0 SP18

Oracle 11.2 is sufficient for target EHP8 with NW 750:

Target Databases

I) Target Database SAP HANA

• Required SAP HANA version is 85 or higher.

Requirements depending on the source database:

1. Oracle

• Oracle version 11.2 or higher if target SAP_BASIS is lower than 751
• Oracle version 12 or higher if target SAP_BASIS is 751 or higher

Best regards,

Hi Murray,

Running your system on EhP8 with Oracle 11g is a risk but you are not running your system here. During DMO migration you are upgrading it and then migrating your DB to HANA. So typically upgrade is happening on shadow and then migration starts where it is purely depend on OS/DB independent process. So it is supported as far as SUM tool allows you to execute.
