Re: Migrating QC 11.0 appserver from one server to other with same siteadmin schema

I had to do this same thing, and opened a case with HP support to get guidance.  This is what they provided.

1. Install the new ALM server and use the same DB server if you want to keep it.
2. During the installation use the same schema password and same passphrases.
3. Make sure you use different site admin schema name because if you use the same name it will fail.
4. Move the repository from the old server from to the new one.
5. Once the new server is ready shut down the old one.
6. Edit the siteadmin.xml file and point it to the old siteadmin schema name. In that way you can keep your users details.
7. Then remove the project and edit the project dbid.xml file in order to point the correct repository location.
8. Restore the project.

On my app server I found the Siteadmin.xml document at

c:\Documents and Settings\All Users\Application Data\HP\ALM\application\20qcbin.war\WEB-INF\siteadmin.xml
