It should just work. Just note that in case of Fedora Server, these are
upstream/Fedora bits which are only tested upstream. So if you for example
break something in Fedora 21 (not likely to happen though ;-) and then get the
change *replicated* to RHEL production instance, I do not think Red Hat support
would be happy with that.

Also, if for example upstream releases FreeIPA 4.2, I would not just plug it in
your production RHEL instance is it would upgrade all the data for 4.2 level -
which should get more downstream testing before Red Hat can rubber stamp it.

TLDR; if you are happy with the upstream level of support (this list/IRC/Trac),
knock yourself out :-)

IMO, they this should not be related (should not break replication). I do not
see anything useful in the error log though. Did you also check
/var/log/messages for the errors log I sent?
