+@section Migration from MIT Kerberos to Heimdal
+
+hpropd can read MIT Kerberos dump in "kdb5_util load_dump version 5" or
+version 6 format.  Simply run:
+@samp{kdb5_util dump}.
+
+To load the MIT Kerberos dump file, use the following command:
+
+@samp{/usr/heimdal/libexec/hprop --database=dump-file --master-key=/var/db/krb5kdc/mit_stash --source=mit-dump --decrypt --stdout | /usr/heimdal/libexec/hpropd --stdin}
+
+kadmin can dump in MIT Kerberos format.  Simply run:
+@samp{kadmin -l dump -f MIT}.
+
+There are some limitations in this functionality.  Users should check
+the input dump and a native dump after loading to check for
+differences.
+
+The Heimdal KDC and kadmind, as well as kadmin -l and the libkadm5srv
+library can read and write MIT KDBs, and can read MIT stash files.  To
+build with KDB support requires having a standalone libdb from MIT
+Kerberos and associated headers, then you can configure Heildal as
+follows:
+
+@samp{./configure ... CPPFLAGS=-I/path-to-mit-db-headers LDFLAGS="-L/path-to-mit-db-object -Wl,-rpath -Wl,/path-to-mit-db-object" LDLIBS=-ldb}
+
+At this time support for MIT Kerberos KDB dump/load format and direct
+KDB access does not include support for PKINIT, or K/M key history,
+constrained delegation, and other advanced features.
+
+Heimdal supports using multiple HDBs at once, with all write going to
+just one HDB.  This allows for entries to be moved to a native HDB from
+an MIT KDB over time as those entries are changed.  Or you can use hprop
+and hpropd.
+
+@section General issues
+
+@section Order in what to do things:
+
+@itemize @bullet
+
+@item Convert the database, check all principals that hprop complains
+about.
+
+@samp{hprop -n --source=<NNN>| hpropd -n}
+
+Replace <NNN> with whatever source you have, like krb4-db or krb4-dump.
+
+@item Run a Kerberos 5 slave for a while.
+
+@c XXX Add you slave first to your kdc list in you kdc.
+
+@item Figure out if it does everything you want it to.
+
+Make sure that all things that you use works for you.
+
+@item Let a small number of controlled users use Kerberos 5 tools.
+
+Find a sample population of your users and check what programs they use,
+you can also check the kdc-log to check what ticket are checked out.
+
+@item Burn the bridge and change the master.
+@item Let all users use the Kerberos 5 tools by default.
