Howto update RHEL 5.10 but not upgrade to 5.11?

I have an application "requirement" to stay at RHEL 5.10. Certainly, I can mount a RHEL 5.10 iso and work from there. However, what I am having trouble with is how to install the relevant updates to RHEL 5.10 since it's release date but not upgrade the point release to 5.11.

Would it be as simple as running yum --releasever=5.10 update?

Any help would be appreciated.

EDIT: In light of the absence of subscription-manager on multiple servers (as recommended by /u/hurron), I am going to do the following:

• all servers are currently <5.10 but are registered to our internal RHN Satellite
• mount RHEL 5.10 iso, create local repo pointing to that, and update to RHEL 5.10
• edit the /etc/yum.conf file to exclude version updates with exclude=redhat-release-5Server-* *5_11*

After that, I will investigate the subscription-manager question but, from what I've seen online so far, it does not support RHN Satellite 5. That may be completely wrong, though. Time to call Red Hat.

EDIT: From what /u/thatmorrowguy suggested, I've opted to work through whatever issues were preventing the group that manages our Satellite server from creating a clone-by-date channel for RHEL 5.10. I think this is best solution that can be had and only requires me to make changes in one place. Thanks, all.
