Hey Joost,

Hope all is well.  Like any other ruleset the revision ruleset can be skimmed.  It is not a process I have actually done before so I don't have the best practices around skimming but if you have any concerns you should reach out to GCS for guidance.

I checked with team on this, they had a couple of things for you to be aware of

- Skimming decisioning rulesets which contain decision data has thrown a few challenges for customers in the past.  In particular around the regeneration of the edit element.  This isn't a revisioning issue, instead a general decisioning one.

- You would need to update the overlay app with the latest skimmed ruleset version

- You would want to conduct skimming in BOE and in Production to keep in sync 

I suggest that it might be a good idea to reach out to GCS via an incident to get the skimming best practices before starting on this endeavour?

Cheers, Alex
