Hi Jeff, sorry that your VAR has not gotten back to you.
Based on your steps above, that looks correct to me. Just ensure that all users are logged off and all files are checked in before doing the database move. Also after updating the registry keys, you may need to restart the Archive and DB services for the new settings to take effect.
A good step by step procedure is in the last chapter in the Installation Guide.
Thank you for your replies and I will begin testing the scenario out and report if I have any issues.
After completing the move in my Dev scenario I was able to move production with only one issue. The email notifications were not being sent and the SMTP setup was giving me a server error. I wasn't able to test the notifications in my Dev environment so I didn't know that I needed to change the DB server name in this registry value for the mail service. On the archive server I changed the value below and notification started sending again.
HKEY_LOCAL_MACHINE\SOFTWARE\SolidWorks\Applications\PDMWorks Enterprise\MailService "Server" = "New SQL Server Instance"
