    What your client is asking for is completely impossible. For starters your direct upgrade part is 8.1.7 (or lower) -> -> -> 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.
