So we are planed to update packages by using "yum update" --command

But here the question was :- If clients got any problem with the new version, we need to Roll-Back to the previous version.

I searched in Google,Got same solution that was as follows
-----------------------------------------------------------
Rolling back yum packages
To configure yum to save rollback information, add the line tsflags=repackage to /etc/yum.conf.

To configure command-line rpm to do the same thing, add the line %_repackage_all_erasures 1 to /etc/rpm/macros (If does not exist, just create it).

If/when you want to rollback to a previous state, perform an rpm update with the --rollback option followed by a date/time specified.

Some examples:
rpm -Uhv --rollback '9:00 am'
rpm -Uhv --rollback '4 hours ago'
rpm -Uhv --rollback 'december 25'.
---------------------------------------------------------------

But i am not sure how to use this for "yum".

Could you please give me the correct way for "Roll-Back for YUM"
And below is the server info
---------------------------------------------------------------
Red-hat release version
cat /etc/issue
CentOS release 5.3 (Final)
-------------------------------------------------------------
AND ALSO GIVE ME IS THERE ANY OTHER WAY TO UPDATE THE TOTAL PACKAGES

Please spell your words out, and don't use so many colors. Your post is very hard to read.

And based on what you posted, you've already GOT the solution. What else do you need??

There you go. You're configuring the yum system to enable rollbacks. So anything you install will be able to be "rolled back", with the command you posted.

Thanks for ur reply and suggestion(i will never use colors from now).

Here i am updating the packages with "yum update"(it will update the all packages at time), but how can "rpm" will help me to roll-back to the previous versions of packages at a time for all packages by using the command " rpm -Uhv --rollback '9:00 am' "
