Blackbaud CRM and Blackbaud Luminate Online sharing one Blackbaud Merchant Service account

Hi! We are using Blackbaud CRM with a Blackbaud Merchant Service account to process our donations, recurring gift payments and pledge installment payments. We are now introducing Luminate Online into our environment with donation forms that will also process donations, recurring gift payments and pledge installment payments. We are thinking of sharing one BBMS account between both BBCRM and LO. I was wondering if anyone had experience with this type of configuration and what they were doing - sharing one BBMS account or having two separate BBMS accounts. The reason we were thinking of one BBMS account is for when credit card information got updated that both applications would be able to see the updates (updates could be done by LO donor, the LO or BBCRM credit card updater tool or one of our staff members in BBCRM). I am not sure if this assumption is correct so I am checking with Blackbaud support on this. Thank you, Dede Smith
