RE: Informix on AIX using logical volume
What has been the tool of choice to get older 5 database to the 7 engine?
Informix doc says you can't use onload and onunload (tbload and tbunload),
since they are from different versions.
I like to hear some experience on this before I have to move my 15 GB
Data Base from 5.x to 7.x.
Thanks!

} hi,
}
} our company provides backup service for a client runnig Informix-online v6(?)

}

} volumes will be used as raw disks for storing informix database.

} vulume with exactly the same size and name as that on the client machine.
} When restoring database from informix-format backup tapes, will there be
} any problem? we were told by the client that informix bypass AIX's logical
} volume manager and access the disk directly . Therefore, the approach will
} not work once the disk gemotry is changed.
}
} I don't believe informix is that stupid and inflexible. if this is true,
} we will be in big trouble. please advise me on this.

} Thanks
