Sage 300 2014 Build 0 to Build 3 (PU3)

Hi

I did not run Day End in the PO module before updating to PU3 Build 3 from Build 0 Sage 300 2014 (AP,AR, GL, PO)

The PU 3 Release Notes mentions that AP, AR, TX and PO have to be activated after PU3 is run. Since I did not do the day end before the update, I get an Incorrect Procedure error when I am trying to activate the PO 6.2 A module.

Can I use a dump of this database and load it on to a 2014 Build 0 machine, do the day end and then dump and load on to the PU 3 machine and activate the PO module?

Is there another way? I have a SQL back up of the database of a day prior.

Thanks
