Hi all, I am going to follow this http://smtpport25.wordpress.com/2010/01/16/migrating-windows-certificate-authority-server-from-windows-2003-standard-to-windows-2008-enterprise-server/ to migrate our windows 2003 CA to Windows 2008 R2. Is there any issue if I follow this article? Thank you.

Hi Elytis, any downtime involed? We only use CA for our RADIUS server for our wireless access. thank you.

Hi Vadims, Thanks for the link. Would it be easier not to import the source server's registry keys and only change two values to the old source server name (which the Active value within the Configuration key or the CommonName value within the CAName key) in the new target server? Thank you. ................................. To analyze the registry file Right-click the .reg file created by exporting the settings from the source CA. Click Edit to open the file in a text editor. If the target CA's computer name is different from the source CA's computer name, search the file for the host name of the source CA computer. For each instance of the host name found, ensure that it is the appropriate value for the target environment. Change the host name, if necessary. Update the CAServerName value. Important If the host name is located in the .reg file as part of the CA name, such as in the Active value within the Configuration key or the CommonName value within the CAName key, do not change the setting. The CA name must not be changed as part of the migration. This means the new target CA must have the old CA's name, even if part of that name is the old CA's host name.

no, it is not enough. You need to edit REG file (as specified in the whitepaper) and import it back.My weblog: http://en-us.sysadmins.lv PowerShell PKI Module: http://pspki.codeplex.com Windows PKI reference: on TechNet wiki

Hi Vadims, Ok and just want to make sure that the two values do not need to be changed in the target server(which theActive value within the Configuration key or theCommonName value within the CAName key), right? Thank you.

Elytis, Thanks for the info. What do I need to do for CA templates? Thank you.
