Best Practices when Adjusting Schedules/ Service Commitments

[wrongway]

Hello community,

we are looking to change the Hours of Service in the Future and for that I need some Understanding of the Best Way to do it. (how its intended by SN)

Since I couldn't find much on docs, i hope to find some helf here. 😀

Situation: 
Business Services  have Service Offerings, the Offerings can have Commitments of different types:

If we look in particular at Service Commitments with the Type 'Availability':

-the Availability-Scores are calculated based on the Schedule we  put behind the Services (e.g. MO-FR 9-5 ).

-this Schedule can change at some point, because of Change of contracts / organisational change

Now my Question:

When those Service Hours/ Schedule change which way is to prefer?

1. Changing and applying a new Schedule to my already existing Service Commitments

    -is there any Risk to loose historical data due to the change of schedule? 

   - would there be a Downside for Reporting?

2. Create new Service Commitments with a new Schedule

    - if so, what would you do with the Service Commitments that are 'outdated'?

    - Thought: Reports on those Service commitments would change and would have to be touched
3. Is there another way I don't see?

I would be thankful for  sources i didn't find or some of your experiences about

adjusting Schedules in Service Commitments.

Thanks a Lot!

Agree mate, it will be like double data but , we dont have any other way as of now.

We have the same issue but because there is no documentation that we can find to explain the implications of changing an availability commitment we are reluctant to do so.
