This has been covered, check the archives more :)
1) how are your current accounts held,
2) there is vconvert command that will convert to a usuable format
3) the archives have an example script you can do if your user names
and passwords are in a text file. Search for post from me, as I
asked this same question.

Subject: [vchkpw] Adding users
I've got hundreds of email addresses to migrate from a different server.
I can easily add username/passwords using vadduser, but would like to
add names to the accounts also. Is there a switch I haven't found?
