Here is a snippet from a program that I use daily that checks for a duplicate file name in the out bucket and renames the in bucket filename if it already exists.

              #check for dup name
               if (-e "$fn_out/$fname") 
               {
                 print "Dup:: $fn_out/$fname\n";
                 
                 my ($name, $ext) = ($fname =~ /^(.+?)(\.[^.]+)?$/);
                       $ext = "" unless $ext;
               my $i = 0;
               while (-e "$fn_out/$fname_new") 
               {
             ++ $i;
             $fname_new = sprintf "$name-%02d$ext", $i;
                       }
                         my $uni = $fname_new;
                         print "New:: $fn_out/$uni\n\n";
                         
                         rename ("$fn_in/$fname", "$fn_out/$uni");
                
                }else{
               
                 rename ("$fn_in/$fname", "$fn_out/$fname"); 
                 print "Dest:: $fn_out/$fname\n\n";
               
               }

$fn_in is the directory for the in bucket of file names. $fn_out is the directory for the out bucket of file names

The critical line is a self incrementing line until it finds a file name that does not exist in the out bucket.

$fname_new = sprintf "$name-%02d$ext", $i;

The format of the file name will be FILENAME-NN.EXT where NN is an incrementing number. You can easily customize this to your likes.

I like using this solution because it works on all platorms and does not require any overhead or modules.
