RE: [Fedora-directory-users] Is it possible to migrate Berkeley 4.2(32bit) based directory to 4.2 (64bit)



Rich,

I have another question regarding the Berkley 4.2 (32bit) "migration" to
4.2 (64 bit):

First of all, the migration process is fine and the new 64 bit Berkley
DB handles even the old files. The search performance is more or less
the same as it was before. However, the add/delete operation is not
good. The performance decreased by 4 times. The entire build process is
identical (besides the enable-64bit switch). Can you shed some light on
that? Do you have the same experience?

Thanks,
-Reinhard

Are you talking about the migration script migrate-ds-admin.pl?  If so,
then yes.  You will first have to export your databases to ldif e.g. for
a Fedora DS 1.0.4 installation:
cd /opt/fedora-ds/slapd-instance/db
../db2ldif -n userRoot -a `pwd`/userRoot.ldif ../db2ldif -n NetscapeRoot
-a `pwd`/NetscapeRoot.ldif ... repeat for each database instance

The migration script will look for a file called
/opt/fedora-ds/slapd-instance/db/<db instance name>.ldif and use that
rather than the binary files.

You should also run the migration script with the -x option to force it
to use cross platform mode.
