@Asad My company went through this process last year in preparation for corporate re-structure and while it was indeed cumbersome and tricky, it is well documented by NetSuite and they have seem a few customer do this. As for consolidation rate, that is where it gets the most tricky because (I presume) when you "re-org" your structure, you will be creating new consolidation relationships and that generates new consolidation rates. This impacts your historical reporting so that is why NetSuite wants to indemnify themselves. You can resolve this by calculating what those new consolidation rates should have been for the historical periods, so that your historical consolidated report remains the same. Bottom line - it's doable, its the best option out there at the moment, and you will need your accounting stakeholders to participate fully.
