upgrade CRS to 4.x from 3.x


How difficult is the upgrade to 4.x from 3.x when CRS is installed on a seprate box and we are running callmanager 4.1. We are using it in a small call center. Would i loose any data if i upgraded to 4.x?

Re: upgrade CRS to 4.x from 3.x

I performed this upgrade over the weekend and am still working with TAC on some issues. I'm told that they haven't seen many of these upgrades yet. Take a look at the Release Notes before you upgrade:

Pay particular attention to the Important Notes section and look at bugs CSCsb20774 and CSCsb69904. Also, if your installation is integrated with Active Directory, be aware that your CallManagers need to be able to write to AD. You can enable that by performing the following steps:

Step 1 Browse to C:\dcdsrvr\config, and open the file,

UMDirectoryConfiguration.ini, in Notepad.



Caution You must open the file in Notepad. Opening the file in another text

editor application may corrupt the file.



Step 2 In the UMDirectoryConfiguration.ini file, locate the key,


Step 3 Change the UserDirectAccess value to true.

Step 4 In Notepad, choose File > Save to save the file.

Step 5 Close the UMDirectoryConfiguration.ini file.

Step 6 Choose Start > Run.

Step 7 Enter regedit in the Open field and click OK.

Step 8 Browse to \\HKEY_LOCAL_MACHINE\Software\Cisco Systems, Inc.\Directory

Configuration within the registry.

Step 9 In the right pane, double-click the DirAccess registry key.

Step 10 Delete the false registry entry and enter true as the new registry


Step 11 Restart the IIS Admin Service and its dependent services by choosing

Start > Programs > Administrative Tools> Services.

Step 12 Right-click IIS Admin Service and then choose Restart.

Step 13 A dialog box prompts you to restart dependent services. These

services may differ depending on your configuration. Click Yes.

Step 14 Restart the dependent services.

Hope this helps.


Re: upgrade CRS to 4.x from 3.x

Another issue that we have now resolved:

There was an HTTP trigger created in Active Directory that did not match any triggers in CRS. In fact, I did not have any HTTP triggers configured. This trigger was keeping the JTAPI subsystem from starting. The TAC engineer that I spoke with said that they had not seen this problem before. Have TAC refer to case# 602121725 if you run into this problem.
