Disconnected Satellite Channel Discrepancy

Hello,

My location has two Red Hat Satellite Servers and because of the environment, one of them requires it to be disconnected. We are currently updating the disconnected satellite by using rhn-satellite-exporter and creating ISOs.

However, we have run into an issue where the disconnected Satellite's channels do not have the same number of RPMs compared to the online version. These Satellite servers were created prior to my arrival and I'm unsure which RPMs are missing and from what dates. We're currently comparing the CSV files of the involved channels to list which specific RPM's are missing. I'd also like to avoid having to re-export several hundred gigs worth of RPMs on DVDs just to fix the 100+ missing RPMs.

Once we get a list of the specific RPMs missing, is there a way to specifically select those packages for export?
