After Migrating an ESX VM (local storage to local storage) I get an error "The parent virtual disk has been modified since the child was created"

Basically the .vmdk files for the C: and D: drives lost their connection with the snapshot vmdk files. I was removing some snapshots to try and make the migration work smoother, and apparently it forgot what we were doing part way through. I used this site to find out how to do basic CID repair

Worked like a champ, now my VM's are alive again on the new ESX Server.
