Why is migrating CentOS 7 off Spacewalk so difficult? #344

Open B3DTech opened 3 years ago

I'm trying to move CentOS 7 systems that are currently using SpaceWalk over to Foreman/Katello/Ansible. Running the bootstrap script causes all sorts of issues that I'm having trouble tracking down.

It was complaining that I couldn't find the subscription-manager-migration repo, so I added the one recommended by candlepin's site. https://copr-be.cloud.fedoraproject.org/results/dgoodwin/subscription-manager/epel-7-x86_64/00273890-subscription-manager/

Try again - this time it complains that the version of subscription manager I have is too new and need to downgrade from 1.24.42-1 to 1.17.6-1. Ok - so I did a yum downgrade.

Next up, it can't find subscription-manager-migration-data RPM. Ugh. Where do I find this one? I see some references for RHEL, but not for CentOS.

Feel like this shouldn't be so frustrating.

Did you ever figure this out as I'm having the same issue? Cannot migrate CentOS7 systems from Spacewalk to Katello due to missing subscription-manager-migration RPM

Did you figured that out? I'm trying to migrate CentOS 7 to Katello but I can't find a mirror for up to date subscription-manager-migration package

This is what we're planning to do, we've tested on one client so far and it seems to work...

  1. Installl subscription-manager on client:

yum install subscription-manager

  1. Deregister client from spacewalk (https://listman.redhat.com/archives/spacewalk-list/2017-June/msg00016.html):

rm /etc/sysconfig/rhn/systemid sed -i 's/enabled *= *1/enabled=0/' /etc/yum/pluginconf.d/rhnplugin.conf systemctl disable rhnsd systemctl disable rhnmd

  1. Register with katello

rpm -Uvh http://**katellohostname**:9090/katello-ca-consumer-latest.noarch.rpm subscription-manager register --org=**org_name** --activationkey=**activationkey**

If you are using remote exectution will also need to add katello public key into authorized_keys of the user on the client and add sudo config (can pull this out of the kickstarts in katello)
