Hi James
There aren't any serialize lines in my /etc/cobbler.modules.conf file.
There were/are in the older version, but in the new one anymore.
This is a copy of the file.

# authn_denyall -- no one (default)

# authn_ldap -- authenticate against LDAP
# authn_spacewalk -- ask Spacewalk/Satellite (experimental)
# authn_pam -- use PAM facilities

I have an old system that is still running SL4 and cobbler 2.0.3.1
I am in the process of configuring a new server that is running SL6.2 and

Cobbler on the new system works perfectly and I now need to "import" or
copy the old systems, repo's profiles, etc, over to the new system.
Doing this manually by copying the files from /var/lib/cobbler/config
cause the following error when trying to restart cobbler
service cobblerd start

removing all the files again, cause cobbler to start properly.
I have tried using replicate, and get the following error:
Remove any serializer lines you have in modules.conf and recopy the
files. That should get you past this error.

Does anyone know what i am doing wrong.. or is there some other way to
move the old systems over?
Unfortunately cobbler does not support replicating between two
different versions, so your best bet is a backup/restore strategy.
