[vchkpw] Upgrading to 5.4.2

[NW]

  I have an ancient machine running vpopmail 3.4.11, and would like to 
replace it with a new machine running 5.4.2.  I'm running into problems 
migrating the accounts, and would like to ask for pointers or help.

  I compiled qmail and vpopmail on the new machine, and verified that 
the entire setup does work.  To migrate the user accounts, I copied the 
~vpopmail/domains directory from the old machine to the new one, but I 
get authentication errors.  (Accounts created on the new machine 
authenticate just fine, but not the migrated accounts).

  Looking through the vpasswd files, I see there are a few minor 
differences in the format, so I massaged the entries for migrated 
domains to match, but I still get authentication errors.

  If I try to manipulate migrated accounts, I am told "Error:  Domain 
does not exist."  If anyone can tell me what I need to do to get the 
migrated accounts to work, I will be very grateful!
