RE: Zero Downtime Upgrade and Migration

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.
