SAP Systems compatibility

[Former Member]

Hello,

We are planning the upgrade of several of our SAP systems:

From SRM 4 to SRM 7

From ECC 5 to ECC 6

From CRM 5 to CRM 7

and portal from EP6 to EP7

I can't find the dependencies between the systems anywhere, I've looked on matrix of compatibility, release information notes and upgrade and install guides.

I need to know if there are any dependencies between these upgrades i.e. does it matter from a SAP / technical perspective which order we do them in and will the upgraded system work with the existing versions of the other systems.

Any help will be much appreciated!

Thank you

Kind regards,

Marcia

Hi Marcia, we're planning an upgrade and going through the same process.

We also used the UDA as mentioned by others.

You might also want to check compatibility with 3rd party tools you currently have by reaching out to the vendors.
