I think you must detect if it's the first write to each logfile.
This is done with a hash (associative arrary).
Code:
...
while(<>) {
  if (/^#(\w+)#(.+)$/) {
    if ($last_name ne $1) {
      close $writeout if $writeout;
      if (!defined $fn{$1}) {
# not yet in hash => rename if present
        if (-f "$1.log") { rename "$1.log","$1.log.old"; }
# put in hash
        $fn{$1}="";
      }
      open($writeout, '>>', "$1.log");
    }
...

This renames to .old. Putting a date is left as an exercise.
