The purpose of this upgrade is to improve the user experience when using the Admin tool to Update ROs. Currently for larger RO dbs (like Barakah) we can run up against memory constraints that do not allow all the ROs to be updated at one time. This is based upon some initial resource where some places were identified where we could improve memory usage. Some of these should benefit PROMS as a whole while others will be specific to the RO Update option in Admin Tools.
