We have a need to migrate the database from a running Production server on

Machine. This is a Transaction Processing system so we want the migration to
happen without any downtime.
We plan to take level "0" back from the Old box , restore to the new box and
then apply the delta using scripts( Unload /load) to bring the data in sync.
Is there a way by which after we have taken a level "0" backup , we can then
take another backup of whatever changed after level "0" and apply that to
database using some informix utility.I am not sure if a Level "1" will do
the job as while the Level "1" is being restored we will have a down time.

Ew . . . ancient!
Anyway, as far as I know, the only way a level 1 can be applied is if
there was a level 0 immediately preceeding.
We moved Informix to new hardware last year and used HDR to handle the
data migration. Wasn't "no downtime", but the total downtime was very
minimal . . . .
Not sure if you could do that with 7.30, though.
