Right, thanks everybody. I just wanted to know if a server migration
from one box to another with an ifx upgrade is possible without
installing the old ifx version first.

Unless it's possible to move the data too. Like when it's installed on
raw partitions and separate drive and the drive is moved to the new box
too. Then there's no point in installing ifx 10 first, correct?

Yes, if you move the physical chunks to the new machine one way or
another, you can just bring the engine up with the new version and it
will perform an in-place upgrade. However, if that fails or there are
any bugs or performance problems you can't get around you may want to
downgrade back to the original version. In that case it would be good
to have already installed the earlier release on the box so you can
just run the onmode reversion option, shutdown, and restart the older
release quickly.
