Migrating from HP to Linux requires an HP export and a Linux import.

A 300gig database would take a few days to export/copy dmp file/import.

That's downtime because I can accept no transactions during the process of export/copy dmp file/import.
Ok now the information is trickling down slowly.

I don't think export would take days for a 300Gig DB. Only the import will.

Advanced replication is possible across platforms.
