Old FAS v2015 version migration issue


I have an old server that needs to be decommissioned and there's Sage Fixed Assets Network Depreciation v2015.1 as well as Sage Fixed Asset Network Server Depreciation v2015.1 on there. Are they different programs or one is the server and one is the client? Customer wants to just move the software to another server and not upgrade. I found what I thought was the install file but it's not installing the database utility only Depreciation Network so I think I have the wrong install file.
