BARS data (when replacing publisher server)

Question

Hi there,
I gonna replace the publisher server and then connect the new publisher with the existing subscriber.
My question is:
When I run BARS and choose the data source server, should I choos both publisher and subscriber server?
Or just publisher server?
I read the BARS document as follows,
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_administration_guide_chapter09186a00807a78ce.html
And "Replacing Servers During the Upgrade" as follows, http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/4_1/install/upgrade/upg413/replace.htm
Those documents don't include the detailed information.
Thanks.

Hi Qinghao, Thanks man!
Good stuff, you are halfway there! The db replication problem and DC directory health problem are most likely related;
Interpreting the Results
The validation results display in the Upgrade Assistant Summary window. At the top of the window, a report summarizes the results for all modules and displays which modules failed, which modules produced warnings, and which modules passed. A link to the folder that contains all log files, including the Upgrade Assistant Summary report, displays also.
To identify a problem with the failed validation module, review the following information that displays in the Summary window:
The first link points to the log file that specifies the error or warning.
Click the first link and search for the error or warning; for example, ERR: or WARN: .
The second link points to the corrective action file that describes the log file error message and recommends the corrective action.
Click the second link to open the corrective action file. Search the corrective action file for the error message that is noted in the log file. Review the description and corrective action.
Caution After you correct all problems that the utility identifies, Cisco strongly recommends that you run the utility again on every server in the cluster before you begin the upgrade.
Obtaining the Log File
You can obtain the results from the utility in the following directory:
C:\Program Files\Common Files\Cisco\Logs\UPGRADEASST (for example, UPGRADEASST-05-15-2003_13.47.58)
To access the log file, click the Summary file.
Tip A link to the log file displays in the Summary window for every failed validation module. To access the log file, click the link in the Summary window.
The Summary.html file, which is the Upgrade Assistant Summary report, provides the exact same information that displays in the Upgrade Assistant Summary window.
Each time that you run the utility, the utility creates a new log folder and new set of log files. The utility does not remove the log files, even if you uninstall the utility. You erase the log files when you reimage the server or manually delete the files.
From this good doc;
Using Cisco CallManager Upgrade Assistant Utility 4.1(3) for Cisco CallManager Release 3.3(5) and Later Releases

**This db replication between Pub and Sub(s) is broken**
The publisher database server upgrade requires that all call-processing processes that the server handles fail over to the configured subscriber servers. Database replication must exist prior to the upgrade, so failover occurs.
This utility verifies the database replication status for all subscriber servers in the cluster. This utility validates that the database contains the latest information about the system. Validation results include Running, Idle, Failed, or Succeeded.
Have a look at this doc for the method to fix the db replication issue;

Hope this helps!
