IntegraMOD

He wants everything that I have modified.

Please correct me if I am wrong.
he installs Integramod 1.50
I backup my datebase
I send him the backup gzip file
he restores database using the gzip I sent


Question, does he have to create a database with the same name as mine?

the db names dont have to match, but the type should, meaning that if you installed the forum using mysql4, the new db should match and not be mysqli. If you do change it, it will still work but may contribute to longer page loads when the site is busy. You can see what db type you used in root/config.cfg
you may also want to dl mysqldumper (http://www.mysqldumper.net/) to do your backup and his restore to ensure compatibility and to be sure you dont exceed your mysql servers .script size/time limit.

he will also need copies of your
includes/def_*.php files
includes/phpbb_security.php
profilcp/functions_profile.php
and your profilcp/def folder

after the initial install, do the db swap, then sync the forums in the acp, then copy over the files

be sure to keep all your original files and db backup in case you run into trouble

once all is running well, copy over these folders
album_mod\upload
files (or whatever folder you use for uploads. youll find it in acp/Attachments/Control Panel)
images

also be sure your backup folder is the same as specified in acp/security/special and that you have the proper amount of admins and mods specified so they dont get banned
