On Set-2006 I was looking for Bugzilla to Mantis (Perl) by Cris Daniluk (http://www.cadencetools.org/projects/bugzilla2mantis/)     

But Nobody didn't find any thing on the web, all web page links are broken or deleted (http://freshmeat.net/redir/bugzilla2mantis/52873/url_tgz/bugzilla2mantis-0.2.tar.gz) ((http://forums.mantisbugtracker.com/viewtopic.php?p=5745&sid=1a679a9fa211306bfd51eb33f7da2579))    

At last, I decided to start my first php script to convert bugs data from bugzilla to mantis (bugzilla2mantis.php).  It is alfa script but its did basic and functional great job.  
I give mantis2bugzilla.php to mantis community to improve bugzilla migration feature

// ------------------------------------------------------------------------------------------
// INSTALL
// ------------------------------------------------------------------------------------------
1) Backup all databases
2) Copy this file to bugzilla web site ( example: /var/www/bugzilla )
3) Modify database parameters "server", "user", "password", "database" ( 'localhost','root','', 'bugzilla' ) in "bz2m_connect()" function 
4) Open "bugzilla2mantis.php" with web browser ( example: localhost:/bugzilla/bugzilla2mantis.php )
5) Check output web page
6) Select all (Ctrl+A). Copy from web browser to test editor. Save to file ( example: mantis.sql )
7) Install mantis website ( http://www.mantisbugtracker.com/ )
8) Modify mantis database from bugzilla data "bugzilla2mantis.php" ( example: mysql -u root bugtracker < mantis.sql )
9) Now, report bugs with mantis ...

On Set-2006 I was looking for Bugzilla to Mantis (Perl) by Cris Daniluk (http://www.cadencetools.org/projects/bugzilla2mantis/)     

But Nobody didn't find any thing on the web, all web page links are broken or deleted (http://freshmeat.net/redir/bugzilla2mantis/52873/url_tgz/bugzilla2mantis-0.2.tar.gz) ((http://forums.mantisbugtracker.com/viewtopic.php?p=5745&sid=1a679a9fa211306bfd51eb33f7da2579))    

At last, I decided to start my first php script to convert bugs data from bugzilla to mantis (bugzilla2mantis.php).  It is alfa script but its did basic and functional great job.  
I give mantis2bugzilla.php to mantis community to improve bugzilla migration feature

// ------------------------------------------------------------------------------------------
// INSTALL
// ------------------------------------------------------------------------------------------
1) Backup all databases
2) Copy this file to bugzilla web site ( example: /var/www/bugzilla )
3) Modify database parameters "server", "user", "password", "database" ( 'localhost','root','', 'bugzilla' ) in "bz2m_connect()" function 
4) Open "bugzilla2mantis.php" with web browser ( example: localhost:/bugzilla/bugzilla2mantis.php )
5) Check output web page
6) Select all (Ctrl+A). Copy from web browser to test editor. Save to file ( example: mantis.sql )
7) Install mantis website ( http://www.mantisbugtracker.com/ )
8) Modify mantis database from bugzilla data "bugzilla2mantis.php" ( example: mysql -u root bugtracker < mantis.sql )
9) Now, report bugs with mantis ... 

// ------------------------------------------------------------------------------------------

On Set-2006 I was looking for Bugzilla to Mantis (Perl) by Cris Daniluk (http://www.cadencetools.org/projects/bugzilla2mantis/)     

But Nobody didn't find any thing on the web, all web page links are broken or deleted (http://freshmeat.net/redir/bugzilla2mantis/52873/url_tgz/bugzilla2mantis-0.2.tar.gz) ((http://forums.mantisbugtracker.com/viewtopic.php?p=5745&sid=1a679a9fa211306bfd51eb33f7da2579))    

At last, I decided to start my first php script to convert bugs data from bugzilla to mantis (bugzilla2mantis.php).  It is alfa script but its did basic and functional great job.  
I give mantis2bugzilla.php to mantis community to improve bugzilla migration feature

// ------------------------------------------------------------------------------------------
// INSTALL
// ------------------------------------------------------------------------------------------
1) Backup all databases
2) Copy this file to bugzilla web site ( example: /var/www/bugzilla )
3) Modify database parameters "server", "user", "password", "database" ( 'localhost','root','', 'bugzilla' ) in "bz2m_connect()" function 
4) Open "bugzilla2mantis.php" with web browser ( example: localhost:/bugzilla/bugzilla2mantis.php )
5) Check output web page
6) Select all (Ctrl+A). Copy from web browser to test editor. Save to file ( example: mantis.sql )
7) Install mantis website ( http://www.mantisbugtracker.com/ )
8) Modify mantis database from bugzilla data "bugzilla2mantis.php" ( example: mysql -u root bugtracker < mantis.sql )
9) Now, report bugs with mantis ... 

// ------------------------------------------------------------------------------------------
// CHANGELOG
// ------------------------------------------------------------------------------------------
2006.09.24 - Clean code and Documentation (afontquerni)
2006.09.16 - Resolve some major bugs (afontquerni)

// README
// ------------------------------------------------------------------------------------------
On Set-2006 I was looking for Bugzilla to Mantis (Perl) by Cris Daniluk (http://www.cadencetools.org/projects/bugzilla2mantis/)     

But Nobody didn't find any thing on the web, all web page links are broken or deleted (http://freshmeat.net/redir/bugzilla2mantis/52873/url_tgz/bugzilla2mantis-0.2.tar.gz) ((http://forums.mantisbugtracker.com/viewtopic.php?p=5745&sid=1a679a9fa211306bfd51eb33f7da2579))    

At last, I decided to start my first php script to convert bugs data from bugzilla to mantis (bugzilla2mantis.php).  It is alfa script but its did basic and functional great job.  
I give mantis2bugzilla.php to mantis community to improve bugzilla migration feature

// ------------------------------------------------------------------------------------------
// INSTALL
// ------------------------------------------------------------------------------------------
1) Backup all databases
2) Copy this file to bugzilla web site ( example: /var/www/bugzilla )
3) Modify database parameters "server", "user", "password", "database" ( 'localhost','root','', 'bugzilla' ) in "bz2m_connect()" function 
4) Open "bugzilla2mantis.php" with web browser ( example: localhost:/bugzilla/bugzilla2mantis.php )
5) Check output web page
6) Select all (Ctrl+A). Copy from web browser to test editor. Save to file ( example: mantis.sql )
7) Install mantis website ( http://www.mantisbugtracker.com/ )
8) Modify mantis database from bugzilla data "bugzilla2mantis.php" ( example: mysql -u root bugtracker < mantis.sql )
9) Now, report bugs with mantis ... 

// ------------------------------------------------------------------------------------------
// CHANGELOG
// ------------------------------------------------------------------------------------------
2016.11.21 - Adaptation for PHP 5.6.16, bugzilla version 5.0.3 and Mantis BT version 1.3.3 - french version (groques)
2006.09.24 - Clean code and Documentation (afontquerni)
2006.09.16 - Resolve some major bugs (afontquerni)

On Set-2006 I was looking for Bugzilla to Mantis (Perl) by Cris Daniluk (http://www.cadencetools.org/projects/bugzilla2mantis/)     

But Nobody didn't find any thing on the web, all web page links are broken or deleted (http://freshmeat.net/redir/bugzilla2mantis/52873/url_tgz/bugzilla2mantis-0.2.tar.gz) ((http://forums.mantisbugtracker.com/viewtopic.php?p=5745&sid=1a679a9fa211306bfd51eb33f7da2579))    

At last, I decided to start my first php script to convert bugs data from bugzilla to mantis (bugzilla2mantis.php).  It is alfa script but its did basic and functional great job.  
I give mantis2bugzilla.php to mantis community to improve bugzilla migration feature

1) Backup all databases
2) Copy this file to bugzilla web site ( example: /var/www/bugzilla )
3) Modify database parameters "server", "user", "password", "database" ( 'localhost','root','', 'bugzilla' ) in "bz2m_connect()" function 
4) Open "bugzilla2mantis.php" with web browser ( example: localhost:/bugzilla/bugzilla2mantis.php )
5) Check output web page
6) Select all (Ctrl+A). Copy from web browser to test editor. Save to file ( example: mantis.sql )
7) Install mantis website ( http://www.mantisbugtracker.com/ )
8) Modify mantis database from bugzilla data "bugzilla2mantis.php" ( example: mysql -u root bugtracker < mantis.sql )
9) Now, report bugs with mantis ...
