Easy way downgarding from release 5.7 to 5.5

[tprizler]

Hi,

I have a server that was originally installed with
Red Hat Enterprise Linux Server release 5.5

And was upgraded using yum update to :
Red Hat Enterprise Linux Server release 5.7

Is there a way to downgrade all packages that were updated during this update??
Meaning going back to release 5.5


Thanks!

Look at /var/log/yum.log, which packages were updated.
Then one could try to
yum downgrade <PACKAGES>

That said,
- why would you want this?
- it is *definitely* not recommended to to so.
Downgrade paths might have side effects, and in general one wants an updated system.
