Good, I suppose you meant "cobbler replicate" !
however to do that I understand that cobblerd should be running on the original server. now that I broken my cobbler installation by upgrading to 2.3.1, I supose I first need to downgrade to 2.2.1 in order to be able from a fresh installed centos 6 with cobbler 2.3.1 to "replicate" from a repaired 2.2.1.
So my first step now is to downgrade the broken original server to 2.2.1 ?
is it just a matter of "yum downgrade cobbler-2.2.1-1.el5" ?
any dependencies problem I might run into ?

Thanks for the advices.

"cobbler reposync" does exactly this.

unfortunatly, there's no clean and secure way to upgrade (yum) from centos 5 to 6, cf
https://www.centos.org/modules/newbb/viewtopic.php?topic_id=32089
everywhere on centos site I see that the only clean way is to reinstall a centos6 from scratch I've got ~400Go of distribs+repos and hundreds of systems recorded on my centos5.7 cobbler broken installation, moving all that to a new cobbler system on centos6 from scratch will be a long journey is there a way to "export" the cobbler "database" (systems, profiles ...) and in parallel moving distrib and repo directories with a simple cp/rsync so that I get all my current cobbler object on a fresh installed centos6 ?

Otherwise, can I downgrade from rpm 2.3.1 to 2.2.1 in order to make my cobbler production server to run again ?

Thanks.

Yes, I had this issue too. The problem is in python.. It's a known issue. I fixed it by upgrading to centos6... Op 11 jan. 2012 18:23 schreef "jehan procaccia" <[email protected] <mailto:[email protected]>> het volgende:
