How would you authenticate then? Remember that it is the hash in
userPassword attribute that is used for actual authentication. If
password-handling plugin cannot calculate to the same hash based on the
plain-text password it was supplied via LDAP bind, how would user
successfully authenticate?

If you migrate this way, you need password hashes, at least.
If you are going to issue users with new passwords, just create all of
them in IPA with these new passwords and ask them to login, at least
once, to IPA self-service.

I don't think is is sufficiently good, at least I wouldn't do it this
way.
