A Vault database can be moved by relocating the corresponding MDFand LDF files from their existing location to another location on the same computer.
Note: The default path for the database files for a Vault is C:\Program Files\Microsoft SQL Server\MSSQL10_50.AUTODESKVAULT\MSSQL\DATA.
MS SQL requires that the user under whom the SQL service is running must have Full Control for the location to where the database is being moved.
It is not necessary that both the MDF and LDF of a given vault be in the same location.
