Restore from backup - EOIO/JMS trouble?

Hi Experts

Please consider the following: A PO system is brought down for upgrade on a Friday, but after a few tests on upgraded sys of adapters processing for 5 hours its decided the upgraded system must be rolled back. On Sunday its restored from backup to old version.

What would be the implications on message processing?

Obviously dublicate check won't work for the msg processed during the time the sys was upgraded

But how about EO and EOIO?

Also, if messages in a inbound JMS queue (lets say sequence #10-20) has been processed by the upgraded system, and its rolled back on Sunday the next megs in the queue will be #21 and not #10 as the system would expect.. How will that work?

Any other considerations? Will there be issues with back end sequencing, DB etc?
