have 10+ TB on unix. 100's of tables. migration to new data center on linux. only have 2 days to export, ftp, import and rebuild indexes. looking for suggestions.

spats, if the operating systems are compatible, you might be able to backup your database on the Unix system and then restore (probably a redirected restore) on the Linux system.

Check out this link for information on what systems you can backup/restore between:
IBM DB2 9.5 Information Center for Linux, UNIX, and Windows

Update your resume and start looking for a new job. You will probably need twice as much time just to transfer 10 TB of stuff by ftp over a dedicated gigabit ethernet link.

Set an HADR pair between the datacenters. Or you can you can use the "poor man's" option, log shipping. Both methods will require that you do a backup and restore, but you will have more than 2 days to do it.

Not only O.S. Look at the prcocessor architicture, especially the 'endianess'. When that differs you cannot use the backup-image. When you make a backup to convert: make sure it is an OFFLINE backup and do not compress.

Yep, it would be nice if both could share a NAS/SAN

unfortunately, the new hardware has been ordered. We are currently running Big Endian and going to Little Endian which are not compatable for restores.
Logging is not an option for our warehouse loads.. too slow...many bulk loads, 2k load jobs a night.
Maybe I should dust-off the resume.....
Thanks all..

Where are you at so we know not to look there

as mentioned before.. : Can port AIX DB2 database to Red Hat DB2?
