When users receive the PAB Replicator message, when they click on the "Copy PAB to.." button, a dialog box pops up with an Execution Security Alert Warning needing action from the user.
This can cause some users to be unsure of what to do with this alert.
This occurs because the design of the PABReplicator database has not been signed by the Design Signing ID for the Organisation. Typically this is an ID that is used to sign any Domino Database applications that might run in the Organisation.
There is no harm caused by Chosing the "Start trusting the Signer to execute this action" and then OK
You will have to do this 2-3 times depending on choice of PAB Copy chosen
To resolve this issue, sign the database; PABReplicator.nsf, and all its elements with an ID that is used to sign Database Applications in the Organisation.
If there are multiple NME consoles being used for migrations then copy this Signed database to all instances of the NME console.
