  Temporarily altering SYSUAF contents? 
 The Question is:
 
I need a script (DCL) to dismail all of my users, change password
"globally",
disuser, backup sysuaf and then restore sysuaf to it's orginal.
I am migrating my users from VMS to dUNIX.  I am trying to move over all
of the mailboxes.  Thanks for the Help!
 
 
 The Answer is:
 
  Assuming you have no SYSUAFALT.DAT file, COPY SYSUAF.DAT to SYSUAFALT.DAT,
  then define the SYSUAF logical name to reference SYSUAFALT.DAT, make your
  changes, then -- when you are ready to disallow logins -- reset the value
  of the UAFALTERNATE system parameter to 1.
 
  Another alternative is to configure and use the POP3 mail server that is
  available with OpenVMS TCP/IP Services.
