Hi All,
I'm preparing for the EHP6 upgrade of our Production system via SUM tool.
I aready have the prepared the xml file, and all the components to be used. And with the xml I have now for production, add-on components A,B, and C are on version 1, like when I performed calculation for dev, qas, and regression systems. We didn't upgrade those components until recently.
So add-on components A,B, and C have been upgraded in non-production systems AFTER the EHP6 upgrade.
Now, they're planning to upgrade those components in production before the EHP6 upgrade.
Considering this, I would like to know if this will have an impact to the xml file I already have prepared.
Even when those components don't have target versions during calculation, since we're not planning on upgrading them before, would this produce an error during Configuration, or Executiion roadmap of SUM?
If yes, what do you think would be the best approach?
If I calculate a new xml after upgrade of those components, this means higher level/patches for all the other components, and that will be applied to production. So a catch-up patching will have to be performed on all the non-production to become aligned. (a lot of work 
)
Let me know if you have clarifications.
Appreciate your immediate feedbacks.
Thank you.
