We suppose that emails won't be lost, but perhaps not all emails will be received especially on large accounts, where Import-User will work for some minutes...
We want all emails/data on database beeing updated to new server SERVERB.
If not, how could we really have updated emails/databases?
Some ideas to solve/improve that issue (does they work?):
1) Set DNS entries on SERVERA of that user to SERVERB before doing the "Import-User"
Posible problem: if an email is received while ImportUser is beeing done, then email will be returned (failed).
2) After the "Import-User" at SERVERB, then set dns entries on SERVERA to SERVERB, and execute again the "Import-User", in order to receive again the data from SERVERA while transfer is beeing done.
Posible problem: Does the second "Import-User" delete all data recevied at SERVERB? So if any email has been received at SERVERB it will be deleted!!!
Any idea or way to do it better?
Thank you.
