Upgrading from 4.1(2) to 4.1(3)

[alan_joseph]

Is it possible to restore a 4.1(2) DB on a 4.1(3) server? I would rather do a fresh install of 4.1(3), and just restore my DB than performing the upgrade process, so as to minimize downtime.

Thanks!

Nope, you will need to run the upgrade process. Unless TAC has some engineering tool that is not published, but typically you must run the upgrade process. Start with 4.1.2, then upgrade to 4.1.3 because it does actually change the database slightly. (add features, updates, etc)

Hi Alan,

This is not a supported method :(

Have a look at the following tech notes;

Procedure

--------------------------------------------------------------------------------

Step 1 Reinstall the operating system on the publisher database server.

Choose the Same Server Recovery option during the operating system installation to ensure that the original information you entered during the initial operating system installation displays in the appropriate fields.

Step 2 Reinstall Cisco CallManager on the publisher database server.

***Make sure that the Cisco CallManager version that is installed on the server matches the version of the latest successful publisher database server backup.***

Step 3 Restore the data to the publisher database server.

Restore Location When You Have Two Different Versions of Cisco CallManager

--------------------------------------------------------------------------------

Tip ***Do a system restore on the same Cisco CallManager version. Changes from release to release cause problems if you try to restore from a different version.***

After a Restore, Database Is Corrupt

Symptom

A backup and restore appear to successfully complete on the publisher and subscriber servers but one database is missing information. Each database shows different versions of the software.

Possible Cause

***A backup was made of one version, and the restore was to a newer software version.***

Recommended Action

***You must do a system restore on the same Cisco CallManager version. Changes from release to release would cause problems if you tried to restore from a different version.***

Hope this helps!

Thanks for the assist ...

Installed the OS-Update 2000.7.sr8 then ran the 4.1(3) upgrade, after searching high and low for the upgrade assistant (why don't they put these things in the same places?) and it installed like a champ.

Ran the 4.1(3)sr4b and now my 7961G-GE phones are registering ... the whole reason for sparking my upgrade.

Thanks.
