Telcor QML with NovaStat Strip meter and go-live with EPIC

We have a go-live date of June 1st with Epic for the hospital.  The lab is staying with SOFT.  If you have recently gone live with Epic, how was the ADT feed handled into Novanet?  Was the legacy system ADT stopped and removed from Novanet at the time of go-live or was it done after go-live.  The plan is to go-live on a Saturday morning.  Nova Biomedical charges for weekend support of this nature. We are trying to find out if it could indeed be done on the following Monday without causing any issues.  Suggestions would be appreciated.
