Avadhani,
What your client is asking for is completely impossible. For
starters your direct upgrade part is 8.1.7 (or lower) -> 8.1.7.4 ->
9.2.0.8 -> 11.2 and your moving os platforms which means a
transportable database migration. Way too many moving parts. What is
the size of the source database? If it's small enough you can go the
export/import route which at least minimizes the downtime. But your not
going to get to 0 on this one.
