Rescheduling Scheduled jobs

question
1

To reschedule scheduled jobs I am currently deleting the previous job and then scheduling a new one within a transaction so if the schedule fails it rolls back the delete:

using (var transaction = new TransactionScope(TransactionScopeOption.Required))
{
	BackgroundJob.Delete(jobId);
	BackgroundJob.Schedule(...);
}

This involves keeping storing the original arguments somewhere so I can reschedule with the original args.

I was wondering whether there was any ramifications to doing the following instead:

new BackgroundJobClient().ChangeState(jobId, new ScheduledState(timespan), ScheduledState.StateName);

This way there is no need to keep the original job arguments around and also is transactional.

Thoughts?
