What needs to be done prior to upgrading a Relativity Data Manager installation?

Problem

What tasks need to be performed before upgrading a v12.x version of Relativity Data Manager to v12.09?

Resolution

As the v12.09 version of Relativity for the windows environment is now available, we recommend that users upgrade to that version to obtain the latest fixes for Relativity. If Relativity system Data Source Names (DSN’s) have been configured with a previous version of Relativity then these are not removed by the uninstall process. These need to be deleted before the 12.09 version is installed, or the following error will be encountered during the install of the 12.09 product.

Install Error:

To avoid the install error, before the previous version of the Relativity Data Manager is uninstalled then any Relativity system DSN’s that have been configured need to be deleted. Once the 12.09 product has been installed, then the Relativity system DSN’s can be added back through the ODBC Data Source Administrator product.

If the previous version of RM Relativity Data Manager has already been uninstalled, then the DSN's need to be removed using the windows Regedit utility. Below are the Registry keys that need to be searched for when using the Regedit tool.

 

Relativity for use with 32bit installations of Windows

For this environment the two keys that need to be checked are:

[HKEY_LOCAL_MACHINE\SOFTWARE\ODBC] and

[HKEY_LOCAL_MACHINE\SOFTWARE\ \ODBC\ODBCINST.INI]

Relativity for use with 64bit installations of Windows

For this environment the two keys that need to be checked are under the Wow6432Node are. The keys are:

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC] and

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBCINST.INI]

Once those keys have been exported, the files can be modified so that they can be used by Regedit to delete the existing keys. The exported files can be used to create files so that Regedit will add the DSN’s back to the registry once 12.09 has been installed.

The following example files show how Regedit can be used to remove the Relativity DSN's installed on a 64bit version of Windows and how to add the system DSN's back to the ODBC Configuration. It is assumed that Relativity has been installed into the default directory structure. The DSN in question is called verify and the one used to run the verify demo.
