Foreman and Proxy plugin versions:

foreman_ansible 6.0.0
foreman_remote_execution 4.1.0
katello 3.17.1

Distribution and version:
CentOS 7 update to date, Kernel 3.10.0.1160.11.1

Other relevant data
Permission had been set like the documentation states it:
chmod -R g+rwX /var/lib/pulp/content
find /var/lib/pulp/content -type d -perm -g-s -exec sudo chmod g+s {} ;
chgrp -R pulp /var/lib/pulp/content

Sounds like you are in a similar boat to what I am in. I read through this post ([ContentMigration] run content-switchover failed - #4 by sajha) And it gave some good pointers but I still am stuck with a non-working pulp system. Hopefully, the stuff posted there might help you recover. I opened a new topic with a detailed writeup of my current issue ([ContentMigration] Failed content migration for Yum repositories) so hopefully we’ll all get some guidance soon.

Seems so, I tried out various things from other posts, but nothing worked.
I hope that we will get support and Foreman doesn’t end like CentOS 8, EoL without any sign.

@foreman-materna thanks for letting us know, since the error is the same as [ContentMigration] run content-switchover failed be sure to follow that thread as we will use that for updates!
