I'm going to open a ticket for one IT team to change the volume of the old service called IVO to the new one called INO. And my question is, should I use to or for? The subject will be something like this: Change 100% of the requests to INO service

Looks good, but what about: Change 100% of the requests for INO service

I'm not sure, but it looks ok. Which is the right and why?

According to espresso English site, I should use to because its kind of "Giving", like this one: I gave the book to my sister

But to be honest, I'm not 100% confident about it.

Your example (Change 100% of the requests to INO service) is grammatically correct and understandable if every request in the system is currently IVO. If not, I would recommend for clarity:

Change 100% of the IVO requests to INO service.

NOTE: "Change 100% of the requests for INO service" indicates that you want to make some change to all the requests that are marked INO, but it is not clear what change is to be made to those requests. In other words, my question would be "To what should I change all the requests for INO service?"

  • Greate, basically using for is right but it changes the meaning, right? Like "change the structure of request" but in my case, I only want a change from IVO to INO. Thank you Aug 4, 2020 at 14:04
