migrate users..and post..to other new forum. HOW?

[cloferba]

hi mates!

i have a user on cpanel wich is ue1ue2...so..i made a db and the db is ue1ue2_foro..and its user is ue1ue2_yo.

now..i want to make other forum..but i dont know how to import all the ue1ue2 forum users..and threads to this new forum..

let me explain:
to make backups i use mysqldumper..wich saves on the backup the db user and db name..

my idea was:
install the new forum..restore de backup of the other forum up a new database (for example db new_forum..and user new_user).

but mysqldumper..only allows to restore backups from one database..to other database with the same name..(so..on cpanel..i cant have 2 same usernames).

how can i keep threads..users and all that in a new forum..with different db name and db user?
