I have used Lacerte software since 1993.   At our office, I am the only one using Lacerte software doing about 20 tax returns annually and paying with REP format.   The main office computer (peer to peer network) is being replaced.   I forget from the last time we bought a new "server" whether I had to download as many old years software and then copy the data files or if there is a way to "move / copy" the programs and files to the new hard drive.   Any suggestions  you can offer from successful prior experience is greatly appreciated.
