Hello @jdempsey  

I indeed wish like my client a small size of FNMS & AP could use FlexeraOne ...but it's likely only when the time Flexera One IT Asset Request feature (new name for App Portal in Flexera One ?:), is this module mature enough as the AP on premise version? And also only when the time Flexera has a 'mature' process similar to moving FNMS On premise to Flexera1 ITAM. I know more and more FNMS users start doing that. I am interested to hear if any App Portal on premise user can migrate their existing AP system 'seamlessly' to Flexera One?  

Is that true these days people can only migrate FNMS On Premise to ITAM and using the existing AP ON premise to connect with ITAM I assume? 

@CharlesW   thank you for your inputs and finding the other thread. The only 'concern' is when something unexpected happening ...for instance, say leave the AP <> FNMS servers communications open (including service gate way as is etc) when the FNMS migration is running.  I am assuming during the FNMS DB being upgrade by hundreds of FNMS scripts (usually it may be couple of hours time....), API still connectable to FNMS ....if an AP user check out a catalog item and consume one license quantity from FNMS at the same moment, what would happen? and particularly if FNMS DB need to rollback whenever any migration error encountered , what's the outcome this AP user checked out result from FNMS, likely license quantity is reverted...but any impact from AP functioning point of view ? etc

This is the main concern ....for the 'worst' case scenario preparation , we need to put both products 'down' during whatever the product migration, in that case we may look into two products migrate at the same windows.

Happy to hear any better suggestions here.

Best Regards

Kevin
