Topic: Migration from EasyForum 2.5
Hi!
Well, after having the lousy EasyForum on our website, we decided to migrate to PunBB, but unfortunately, we needed to keep the current users and posts but no migration tool was available. So, we quicky hacked two perl scripts which parse the username database and the thread directory and spit out SQL code. Obviosly it was tailored for our needs and if someone needs to use it, it will need some minor modifying.
But hey, at least they'll have something to start with, which we didn't.
Anyways, here's the code...
Users Migration
#!/usr/bin/perl
open(DATAFILE,"/path/to/-members.php");
$id=9;
while (defined ($line = <DATAFILE>))
{
chomp $line;
@parts = split(/:/,$line);
# $parts[0]; # Username
# $parts[2]; # Hashed Password
# $parts[4]; # Email
# $parts[6]; # Description
$parts[6]="" if ($parts[6] eq "-");
$id++;
$parts[6] =~ s/(['"])/\\$1/g;
print "INSERT INTO users VALUES($id,4,'$parts[0]','$parts[2]','$parts[4]',NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,0,NULL,NULL,NULL,1,0,0,1,1,1,1,1,1,'Catalan','Oxygen',0,NULL,1189078770,'1.2.3.4',0,NULL,NULL,NULL);\n";
}Posts Migration
#!/usr/bin/perl
sub get_id
{
open(USERSFILE,"/path/to/-members.php");
while (defined ($line2 = <USERSFILE>))
{
chomp $line2;
@parts2 = split(/:/,$line2);
push @users,$parts2[0];
}
$id=9;
foreach $user (@users)
{
chomp $user;
$id++;
return $id if (lc($_[0]) eq lc($user));
}
return 0;
}
sub thread
{
open(DATAFILE,"/path/to/threads/$_[0]");
$first=1;
$topicid=$_[1];
$num=0;
while (defined ($line = <DATAFILE>))
{
chomp $line;
@parts = split(/\:\|\:/,$line);
$posts_thread++;
