Dentrix said only 3 folders needed but instructions said also Template Folder

I Setup a RoboCopy Script to copy the Dentrix DTXCommon Folder from T:\ to M:\Dentrix\Common
Script Locations: C:\Backups and M:\Scripts4Backups
net use T: \\Server2008\DTXCommon
First Run had some errors so will look at adding Shadow Copy

Dexis did not have a paper to refer to but Kyle called back after Email sent to Support and gave these instructions.
On old Server turn off SQL Services
Copy "DEXIS Imaging Suite" Folder to new Server
Run \DEXIS Imaging Suite\Data\Setup\Setup.exe
This will install SQL 2005 and then run SQL Server Configuration Manager under Microsoft SQL Server 2005 Configuration Tools
Choose TCP/IP enabled. Dexis should find data and attach. If not, call them to fix. Do not try to fix yourself.
