SRM upgrade

[Former Member]

Hi everybody,

I look for someone who has experience in upgrade from SRM 5.0 to SRM 7.0 and who can give us an advice if it is better to upgrade the existing SAP SRM 5.0 to SRM 7.0 or is it better to build the SRM 7.0 completly new?

And why is the one way better then the other?

In the existing SAP SRM 5.0 are a lot of developments.

Many thanks in advance.

Best regards

Hi! I have experienced both, and there are pros and cons:

Upgrading:

Main advantage: Most of the configuration is retained, both at the ECC- and SRM-side.

Disadvantage: Go-live-process requires system downtime. Need to be scheduled and managed tightly.

New installation:

Advantage: Easy to control go-live process as no downtime is required. Always nice with a fresh system with. Easier to get rid of modifications.

Disadvantage: Lots of work if you want to migrate old documents. All configuration, new logical systems etc. need to be performed and created.

Good luck with the project!

Hi. You should be able to perform an upgrade during a weekend, startring early friday - but it will involve a few consultants.

The most heavy burden is for the Basis consultants to bear, as they need to install all of the software on each system incl. production systems. Probably you also need Portal- and Authorization-consultants during the weekend. The client specific SRM customizing could be limited to workflow and user-roles, refresh POWL etc. The rest should be inlcuded in transports.

Also bear in mind that once you start upgrading in the production-environment, you will not be able to perform error correction involving transports from development system to production system ... you will need to perform such in QA- or production environment directly
