Does IBM-AIX read HP-UX files? If it does then you can copy the files and create that \
database with "new control files" which will be the fastest way.

With the amount of data, I would not import the indexes but create them after using \
the unrecoverable option. Also have the archive log mode turned off. I would guess it \
will be more than hours and hopefully less than a week.

By the way, why the switch from HP to IBM? The downtime of the DW must surely be more \
than the cost difference between the two.

  Hi List,

  Could someone please help me?

  Assumption situation - Platform migration of Oracle DW on Oracle DB (data
  volume 3.5 TB) from HP-UX to IBM-AIX

    1.. DB migration; it is correct to use Export/Import technique/method in
  the above assumption?
    2..  Witch is the time frame in a worst case for this (how many hours,
  days or weeks!!)?
    3.. It is possible to apply the mentioned technique or some other (witch
  one?) in uptime, totally or partially?
    4.. Witches are the main tasks to consider in a planning schedule?
    5.. Witches are the time frames associated to these tasks?

  Thanks
  Arménio Teles
