I am migrating users and computers from one forest to another forest, we are going to use SIDHitory for shared folders and roaming profiles. I have doubt if SIDHistory will still work even after the source Domain is gone. I found similar question here https://social.technet.microsoft.com/Forums/en-US/6ba40b25-5e37-449d-9779-7a348ab8b1a9/sidhistory-question-once-a-domain-is-gone?forum=winserverDS.
However I could not find any official MS document where it clearly mentions that SID History works even after the Domain is gone.
