This Perl program is designed for one thing and one thing only: open one old database Perl file with line @arrays, read them, manipulate them, sort them and merge them into the format of a newer existing database. It will delete the old database files from the server if you select that option. The program will call both databases, older and newer, convert the older to reflect the format of the newer, sort and merge it with the newer and create a new database file in that directory. That's it. Will save you hours of tedious work, especially if you database is large.
