The initial setup was fine and straightforward. The migration process related to Microsoft Parallel Data Warehouse has been going on for a month in my company. We have multiple labs, of which it was possible to load the data in 47 labs. With one lab, it took almost a week to load the data since the data count was in millions, due to which it initially failed multiple times, creating a huge issue for us. It's all done right now, but we have faced issues in the past. In our company, we created new databases in the new SQL Server. We replicated the databases, and then we got the data from there.
