Suspending Background Jobs during an upgrade downtime

Hi

We are upgrading to ECC 6.0 soon and there will be an extended downtime to facilitate the cutover.

The downtime will cover two days so there may be some daily jobs that will fall twice within the downtime. If I run program BTCTRNS1 to suspend Background jobs, and the run BTCTRNS2 to recommence, will the daily jobs that were scheduled to tun twice during the downtime, actually run twice or will only the most recent instance run?

Similarly for hourly jobs, when I run BTCTRNS2 will all hourly jobs that were due to run in the downtime, actually run when i execute BTCTRNS2 to recommence?
