NFS mount schema is the same and standard 2307bis so there is no
difference between the versions.
The only issue can be the location of the container since we did some
rearrangement of the tree recently. But there is no crypto or hashes
there so dumping the cn=automount and loading it into the new version
should be straightforward exercise.
For the users migrate-ds should be used then. It will take user accounts
from the old installation and move to the new one.
If you use SSSD on the client in the migration mode then it will
recreated migrated kerberos hashes behind the scenes as soon as you log
into a client machine using SSSD after migration.
If migrate-ds does not work for you then we need to know all the details
and logs of what went wrong so that we can fix the issue.

The procedure described above, i.e. using SSSD on the client will solve
the problem of the password migration if you care.

This is your decision to make.

They are not "migratable" versions. Frankly I have not heard of any
product of such complexity that would support migration between the
alpha-beta-rc drops. Sorry but your expectation is wrong. It is our
fault that we have not clearly stated it but this is the case.

And yes, just to set expectations straight, when we release IPA v2 we
expect it to be a fresh install and users migrated to it using
migrate-ds and passwords migrated using SSSD or a special migration page
we provide. Other parts of the tree can be migrated piecemeal and we
will be happy to help you do it if migrating this part of information is
possible. For example migrating hosts and service will not be possible
but sudo, HBAC, DNS etc. will be, so discretion should be used depending
upon what you have in your deployment.

However if we are talking about 10-20 accounts it might be easier to
recreate them manually or with a simple script.
Overall we appreciate your business and would be glad to help within the
reasonable expectations.
