Icy Phoenix

Hallo,
I've a phpbb (ver. 2.0.21) forum into a mk portal 1.1.1 and FAP mod 1.4.1.
I'd like migrate all to ip_20070405_101111_rc.
I've seen there is a file (update_to_ip.php) for a easy update, but I'm not sure about:
1. When I update, are in the new forum all data I've now in phpbb 2.0.21 forum (f.e. i've attach_mod 2.45 now: all attached files are into a folder called "files" into phpbb root. Have I manually transfer all files in "files" folder to new "files" folder)?;
2. Now all my FAP images are into a subfolder called "upload" into "album_mod" folder (mysite/forum/album_mod/upload). In icyfoenix, as I can see, the images are into another folder called "album" (ip/files/album). Have I manually transfer all files (cache too) ?
Thanks in advance
