Restoring historical data

SOLVED

History of Question:
* The SAGE 100 Con database had over 30 companies in it and performance was "sluggish."
* Backups were made of all companies and copied to another server for safekeeping.
* A 2nd SQL instance was created and all companies between 2 years ago and 2010 were moved to the 2nd SQL instance. (about 18-20 companies)
* Three companies for this year and last year were retained in the original database.
* Companies earlier than 2010 were not retained in any database (about 10-12 companies)

Questions:
* The historical data prior to 2010 has been requested made available so should it go into the 2nd instance or should a 3rd instance of SQL be created?
* What is the procedure to restore the files from the other server to Sage's 2nd or 3rd instance?

I'd rather look foolish in asking the question than in losing the data.
