That should not pose any real problems :)
You`re right. ;-)
We used a cross-link cable between the two machines to transfer the data over their gigabit link. Both systems had three 10k rpm SCSI disks in hardware RAID 5 which pushed data at around 20 mb/s. That took around 20 minutes. Now for the migration script, that took about 1:30 hours to run on a single Intel Xeon 2.80GHz.
That sounds really good. I´ve to test some things and I think I`ll migrate the old mboxes. Thanks very much. Cheers Torsten
