I wasn't sure which forum to post this under, so the 'Getting Started' seemed the most applicable to my situation as I have never really dealt with MSSQL before.
I have a client that has POS software called Restaurant Pro Express (RPE) from www.pcamerica.com
Their old POS computer had a hardware failure, but I was able to attach the hard-drive to another computer and recover the data. RPE uses a MSSQL database system. However, my client doesn't seem to make backups very often - the last one is dated January 5, 2015. I was able to copy the C:\Program Files\Microsoft SQL Server\ folder over which contained the instance as well as all the data files - and has up-to-date information. The instance in the recovered Microsoft SQL Server folder was called MSSQL.1. I installed the RPE software on their new computer, and it too now has an instance called MSSQL10_50.PCAMERICA. The new computer is using MSSQL 2008 R2, while I believe the old computer would have been using MSSQL 2005.
I am no DBA expert, especially when it comes to MSSQL. Is is possible to 'restore' the database from the 'raw' .mdf and .ldf files of the old computer to the new computer / database instance? If so, how should I proceed?
