<PRE>2011/6/9 Olav Vitters &lt;<A HREF="https://www.mageia.org/mailman/listinfo/mageia-dev">olav at vitters.nl</A>&gt;:
&gt;<i> Hello,
</I>&gt;<i>
</I>&gt;<i> Now that GNOME3 is being imported to Cauldron, I'd like to switch my
</I>&gt;<i> Mandriva Cooker installation to Cauldron.
</I>&gt;<i>
</I>&gt;<i> However, Cooker has a different rpm for a while and I have that
</I>&gt;<i> installed.
</I>&gt;<i>
</I>&gt;<i> I'm guessing if I attempt to switch to Cauldron, it likely cannot read
</I>&gt;<i> the rpm5 database.
</I>&gt;<i>
</I>&gt;<i> I can only think of a few things:
</I>&gt;<i> 1. Create a new partition, install Mageia 1 on that, switch to Cauldron,
</I>&gt;<i> install all the non-automatic installed packages, copy stuff from the
</I>&gt;<i> Cauldron partition to the existing one
</I>&gt;<i> -&gt; Not too sure about the copying. I've modified various things over the
</I>&gt;<i> years (e.g. special Postfix setup and so on)
</I>&gt;<i> 2. Just attempt to install Cauldron, forcefully reinstall the packages,
</I>&gt;<i> and ignore the rpm difference
</I>&gt;<i> -&gt; I think this will fail though
</I>&gt;<i> 3. Somehow export/downgrade the 'rpm5' info to rpm4. Is this possible
</I>&gt;<i> and how?
</I>Yes, there's a URPM::DB::convert() function in URPM &gt;= 4.8 which can do this,
and there's also a standalone utility provided with rpm5
(/usr/lib/rpm/dbconvert)
which also can do this.

You want to convert the format from btree, big endian to hash, little
endian in order
for the rpmdb to work with rpm &lt;= 5.2.
