For language translation earlier we were using separate application (having same ruleset in both application except language specific ruleset) and now we have decommissioned the language specific application and not using at all but as those un-used application still exists in system we are getting severity 2  ABVRulesetInManyApplications warning. So for getting rid of these sev 2 warning we are thinking of completely deleting all the version this un-used application. So I have below questions:

1. How this will impact the in-flight work objects.

2. How to analyze the impact and what corrective actions need to be taken to have no impact on in-flight work objects.
